buckshot will not reliable penetrate a decent vest
but a 30-06 deer rifle will drill through one deputy and get the one behind him too...
Sorry, but unless you are loading that 30-06 to 300W. Mag. or above, and using 30-06 WW II armor piercing bullets, there is armor available to stop a mere 30-06 WW II black tip.
As a matter of fact, ability to stop a 30-06 black tip is the test for one class of vest.
A .300-.378 will penetrate any vest, but such a handgun would be best left to the proverbial 800 pound gorilla and its huge hand.
PS Even the gorilla would be bleeding from its ears if it touched off such a round in a room.
PPS Lawyers are the weapon of choice against out of control LEOs.
Lawyers for the most part are scum
and most cops wear a vest they can comfortably wear all day...and the SWAT boys carry the heavy stuff...
and PS I come from a family of cops...not to say I know their gear, but I do know cops...Dad past away(old age) 5 years ago...he was a good cop...but my mothers brother was NOT.
