Only downside I see is for fed trucks but other than that I agree. In any other situation but a truck full of gold bars the cost and strategic planning of using a vest is worth having looser rules in its use.
Honestly this reminds me we need to get the swat rules and wiki up to date still tbh, I have no problem gathering my PSAs and adding them to the written rules. At least theres a lot less because mako said so now lmao
