I am not overly concerned with profiling. I wear all current issue tactical gear & on occasion have been worried about harassment. I carry a legal length pocket knife, have no warrants & dont do drugs. Of course i have a felony record, a dd214 with combat MOS's, no drivers license,bank accounts etc. I am a vet & dont much participate in society. The line between patriot & domestic terrorist is thin, but I dont care enough about mainstream issues to care. You wont find me protesting ever! No occupy bullshit to get free food & gear. No g8 summits, nada. I think if you dont appear on their radar during these types of activities you should be safe. I do fear that hitchhiking & riding trains some day will get us harassed by homeland insecurity or other authorities that attempt to destroy more freedom here. Luckily that day hasnt came yet. So I trespass on railroad property, have some priors, drink a bit, travel some & dont work. Kinda sounds like most returning combat vets throughout US history. I have done enough for this country.
