Police tend to get suspicious when they see somebody jump out of a moving car - especially one they're trying to pull over

Boston Police report arresting a Dorchester man they say was packing a loaded firearm when he jumped out of a car that was still moving as they tried to pull its driver over for a traffic infraction.

Police say the car "was slowing to a stop" outside 12 Powellton Rd. around 3 p.m. on Thursday when Tyrre Herring, 19, of Dorchester, got out of the car.

As suspect was exiting the vehicle, officers promptly observed his right hand clutching a firearm that was sticking out of the waistband of his pants. With the protection and safety of all in the immediate area on their minds, officers immediately began to chase the suspect through several backyards and over fences until they were able to apprehend him behind 5 Strathcona Street. The officers later recovered a loaded .40 caliber Smith & Wesson SD40 VE handgun and other material evidence which the suspect had discarded during the foot chase.

Herring was charged with unlawful possession of a firearm, unlawful possession of ammunition and trespassing, police say.

Innocent, etc.
