Larry Davidson compares the fresh soft-shell crabs at Roche Bros. and the Legal Seafood fish market and finds the Roche Bros. versions "tastier, fresher-tasting, and plumper" than the ones at Legal.

He also wonders why the Shaw's and Stop & Shop in Dorchester can't be as well stocked and have as good employees as the Roche Bros. in West Roxbury.

Adam Pieniazek provides the photographic proof.

Boston Police report arresting a Roxbury dude and a Dorchester teenager around 10:40 p.m. yesterday on charges they stole a pair of mountain bikes from Charter and Michaelangelo streets. Police say the pair were caught on the bikes, and that witnesses had reported seeing them on foot earlier in the evening. Unlike Tuesday's alleged North End bike thief, they did not attempt to escape by jumping into the harbor.

Meanwhile, in Dorchester, police report that Luther Boyd, 42, ended a lengthy argument with his brother-in-law by plunging a knife into him around 4 p.m. yesterday at 142 Harwood St.:

Officers spoke to a witness who reported that the two men, the suspect and the victim who are brothers-in law, had been arguing for most of the week and the argument escalated into a physical fight on this day.

Police say they found Boyd in the kitchen with his brother-in-law lying there, bleeding. He was taken to Boston Medical Center in critical condition.

Innocent, etc.

Boston Police report a teen, 19, was shot at 164 Howard Ave. in Roxbury around 11:50 p.m. yesterday.

An off-duty officer quickly reported a suspicious vehicle and police, responding to 392 Columbia Rd., found a car with a broken rear window, blood everywhere, leading up to an apartment there. Then, another car drove up and a bleeding man got out; he was taken to the hospital. Police say this guy, Duante H. Beal, 20, of Dorchester, was the shooter and he now faces a variety of charges, including armed assault with intent to murder.

Meanwhile, police report that when a clerk at Lambert's, 777 Morrissey Blvd. tried to stop a woman and a gaggle of kids from walking out with salads they hadn't paid for this past Friday, one kid stopped, the rest kept walking and the woman threw the salad container at the clerk and, for good measure, threw a punch.

Police, again aided by an off-duty officer, say they quickly caught up with Christal C. Campbell, 39, of Dorchester, and charged her with charged with assault and battery by means of a dangerous weapon (the salad?) and assault and battery. And they discovered she was already wanted on 26 other charges, including escape from jail.

In the Bay State Banner last month, Bobby Constantino wrote about a teen witness to a brutal Dorchester shooting who had to choose between not testifying and going to jail or testifying and being relocated out of state to protect him. Now the defendant in the case has been found innocent; Constantino writes the ripples extend far beyond a kid who essentially gave up everything he knew:

... Everyone that knows Thomas in the neighborhood, from peers to relatives and friends -- and we are talking over 100 people here -- has heard about what happened to him after he testified. They now know that if they testify in a case they will have to give up everything important to them here and move away.

As a result of this case, there are now at least one hundred people that will never ever step forward if they see a shooting or have information that could help the police. And given that there are hundreds of shooting cases just like this one year after year, the number of people that feel this way is growing.

When law-abiding residents that witness crimes must choose between coming forward and giving up life as they know it, it is an indication that we are failing as a society.

Boston Police report arresting William Terrell Hart, 22, of Brockton on charges he tried to gun down a man at 103 Devon St. around 4:20 yesterday afternoon.

The man is in serious condition at Boston Medical Center, police say.

Hart will be arraigned on charges of assault with intent to murder, aggravated assault, assault and battery by means of a dangerous weapon, unlawful possession of a firearm, unlawful possession of ammunition, and unlawfully carrying a loaded firearm on a public way.

Channel 4 reports the three, aged 12 13, 14 and 15, were standing on the third-floor porch of a triple decker shortly after midnight when somebody drove up and opened fire. All are expected to recover. The Globe gives the address as 60 Homes Ave.; says the shootings come after a man was shot at 107 Devon St. around 4:40 p.m. yesterday.

This time, it was a woman walking across the driveway of the Sheraton on Dalton Street shortly after 10 p.m., yesterday, Boston Police report, adding this incident had a better ending than the last such incident - she's expected to survive.

As is the woman run down by a motorcycle around 8:20 p.m. yesterday at King and Adams street in Dorchester, driven by a guy who, police say, sped off in a panic when asked to pull over by a couple of officers because he doesn't have a license. In this case, police arrested the operator, Leigh Perry, 36, of Dorchester, on a variety of charges.

Also yesterday, police arrested Reynold Best, 42, of Randolph - who, on seeing his illegally parked car getting hitched up to get towed away on Bismarck Street in Mattapan yesterday afternoon, allegedly pulled a knife on the tow operator, then stole a GPS unit and car jack out of the truck, the latter which he then used to dent the truck:

When asked to explain how the victim's GPS system ended up in his car, the suspect stated, "He was taking something of mine so I took something of his."

Innocent, etc.

Police yesterday charged a Dorchester man with shooting a teenager in the back as the kid attempted to run away from him on June 26.

Police say that after shooting the teen at Nightingale and Wales streets around 2:50 p.m., Gevaughn Clark, 21, of Dorchester, got back in his car and, while attempting to put his gun in his pocket, managed to fire a shot into his own leg. They say he showed up later in the day at Carney Hospital with a bullet hole that started on his right hip and ended on the other side of his right leg:

Gevaughn Clark had stated that he got shot at the corner of Wales St. and Nightingale St. but stated he was walking to his car not driving.

Police say an investigation showed otherwise and that they recovered the bullet from the floor of his car. The teen's injuries were not life threatening.
