The word "allow" does not exist in law.
Laws prohibit "things" or "actions", OR require actions.
There is no such thing as "allow" in law. This is not the 16t century living under a king who by decree "allowed things or actions".
When the phuck are people going to wake up?
If a search warrant were issued for the home of every Boston police officer, I'd bet a years pay that 90% of them had illegal guns or other contraband in their possession.
When I was a teenager, a friend of mine from Washington state had an uncle on the Boston PD. My friend showed me a chest of drawers at the house, FULL of weapons illegally confiscated from people on the streets of Boston and never turned in as evidence, to include sawed off shotguns, sawed off rifles, all kinds of pistols, brass knuckles, knives, billy clubs, saps, pipes with friction tape handles, all kinds of zip guns, straight razors, ice picks, shanks, boxes of ammo and loose ammo, The drawers were so full they could hardly be closed.
I know of one case where more than 50% of drug evidence seized was never turned in.....thousands of pills.
I cannot imagine things have changed much since.
