I just get a call on my cell and if I don't know the number I usually let it go to voice mail, so I don't answer it and whoever it was leaves a voice message;

"Please call Officer John Thompson back and I'll explain the trouble you're in"...................well, I reverse check the number and I think it's one of my goofy friends in Michigan, I haven't called him back yet, but I know for sure it's not a cops number, I know 100% that I haven't done anything wrong anyway and a cop doesn't leave a message like that, now it's time to think how I get him back.
