I'm going to have to agree with the others. You will be strung up when it comes your day in court. I really don't see any way a defense attorney will be able to have a jury not consider you a wanna-be assassin.
Granted it does have benefits such as protecting your hearing but these in no way out-weigh the risks.
One other thing that just hit me. I have several legally owned suppressors. What do you want to bet just the fact that I own these will be used against me in court, should I ever find myself in that position. Just a thought.
