Agreed in the virtue signalling part, but the safe use of actual weapons in these situations requires a line out, not a fucking BFA. A BFA allows the gas system to have back pressure to cycle a blank, it's not a good damned bullet trap.
I got no beef with using an actual weapon, but line outs are a necessity to doing so. Purposely leaving ammo in the vicinity or on your person is totally unacceptable. Full stop, end of fucking story.
The military learned this lesson years ago, and it was NOT "newbies" who shot each other. The LE community see's these lessons reared almost on an annual basis as well, almost exclusively when a class comes back from lunch and the staff fail to do a line out.
