I consider that question to be more than a stretch but just for sake of entertaining it, what difference would it make if you did? First, I doubt "Nobody heard the shot." rises to probable cause for a search warrant. If it did, they'd check your gun and absolute worst case scenario if the calibers match they'd have to run ballistics tests. If they're shot with a 45 and your silencer is 9mm, there's not much of a case, eh? There's so many reasons that such a thing is unimaginable that I'd be more concerned about alien abductions.
Still happily answering to the call-sign Peetza.
The problem, as you so eloquently put it, is choice.
He is no fool who gives what he can not keep to gain what he can not lose.
