Should have blasted it. Where it may be illegal to shoot in your area, it is legal to do so for protection. In other words, blast it, and tell them it was coming to get you and you had no other choice.
People that own suppressors are law abiding citizens. Do you think that they are going to risk losing their cans because they want to throw 50lbs of deer meat in the freezer on the down low?
Up home you were allowed one as well, and could purchase a doe tag, and a bonus doe tag if you were lucky. Four points on one side to be legal, but I rarely left the front yard.
With proper bullet selection, and proper shot placement you should be just fine. If it takes you 4 shots to kill a deer with a tirty tirty, then it probably isn't for you.
