Everyday before I get on 90 I hang a sign on my truck that says NO POLICE. I set the cruise at 66 and never get pulled over for speeding. So theres the proof that it works.
I'm just guessing she (he) thinks that if she (he) includes the statement "NO POLICE", they won't show up and she'll (he'll) be safe from prosecution!! Smart...
Probably a scam. If it's not, I think it might mean they don't accept Leo clients. There are thousands of Leo clients out there. Once touring (I think in Denver) I saw a "No lawyers" ad and in Atlanta I saw a "no irish" both made me die laughing. It made me remember my Irish grandfather's vintage "Irish need not apply" sign in his garage.
