Most of American law is backed by propaganda, usually in the form of signs and television shows. Of course, "No Hunting/Fishing/Whatevering" signs are not going to fine, arrest, or shoot you, and anyone who's taken Clue 110 will realize that LE personnel are not like the actors on television.They are like any Babylonian (civilized) worker -- they work from nine to five, eat garbage, don't give a fuck about their jobs, and then drive home to harass their families. Also, when it comes to general crime, they show up after they get a phone call.
And LE is only able to catch people who are slightly dumber than they are, so as long as you aren't doing stupid shit on behalf of money, and are generally clever, then all should be well.
The armies of Babylon are only unmatched in physical strength, but they ain't so smart.
So the best thing to assume is that all Babylonians are narcs. Not "treat" all Babylonians as narcs; all Babylonians are narcs. They are the people who will most certainly call in on you. Especially over where I'm at, where people have this vile idea of being opposed to directly killing animals, but will finance agriculture and all industries it enables to torture, mutilate, and exterminate everything. I would not recommend urban hunting unless it can be done at night, otherwise you will have to deal with greater risks. Of course, doing any hunting at night will need some special tools, unless you're a pretty decent ninja. The easiest thing to do would be fishing. It's great at night, everyone is asleep, and it's still just as fun.
You also don't necessarily need to lug around weapons, tools or whatever. Whenever I go pole fishing, I just stash the pole under a pile of sticks right where I'm fishing. The same can be done with anything else. No one will steal it because they aren't looking for it, and typically don't come anywhere near it. The more expedient/primitive the weapons are, the better, since they are generally easy to make, and it doesn't really matter if they get lost. Just keep track of where you hide it.
