The writer is either assuming facts not in evidence, or is working as a propagandist for the cops. In any event, it’s a blogger I wouldn’t waste any time reading.
Is this the same city where that happened?
The M79 is a 40mm grenade launcher. They can fire high explosive, canister, smoke/signalling/illumination rounds including white phosphorus, CS tear gas, a round with 48 rubber balls of .48” diameter regarded as lethal under 10 meters and ineffective over 30 meters. In Vietnam, empty cartridges were sometimes modified into “super shotgun shells”.
West Springfield got two grenade launchers? I guess they need itfor the Big E crowds...
I really doubt that they have 40 mm launchers. Much more likely they have 37 mm (1.5 inch) launchers designed for civilian law enforcement tear gas, baton shells, etc. They have been around since at least the 30’s.
They look like M-79s but are deliberately sub caliber so military rounds cannot be used with them. I have fired plenty of rounds with them.
