So, you think that having been proud of a country that required evidence to convict people means I'm PRO murder, rape, stealing, assault, arson and terrorism? As you point out, all those things are already against the law (except terrorism which has no definition beyond "If the government decides you've done it"). Why would you believe it's a bad thing that the government protects us from itself? Why would you believe it's a good thing that the government should be able to strip that protection from any US Citizen without a trial?
Yes, that's what the patch is about. So what? I can head into the nearest police station and confess to killing Kennedy and they won't execute me for treason. Y'know why? Yep, it's that whole nation of law that requires evidence for convictions thing.
So, you don't like bikers. I'll tell you something: Neither do I (though in my case, it's mostly because they deliberately make their motorcycles louder - that really pisses me off). If you've proof of their crimes, you should come forward and have them prosecuted. If you don't have anything more than rumor, you should probably stop posting on internet forums that their Constitutional rights should be violated and they be declared treats to national security.
