A frequent travel companion:
a) has never had an “on the books” job;
b) seldom carries luggage or appropriate ID;
c) is likely to display excitement and agitation when approached by officers;
d) doesn’t speak English;
e) is non-white;
f) under 25; and
f) is distantly related to a family associated with known Columbian heroin smugglers.
Am I likely to be pulled over?
I think the OP should setter down a bit. There’s no reason to believe the cops are going to hound your friend. Unless maybe you happen to be German, shepherds don’t recieve any more scrutiny than the usual mutts who travel frequently. Don’t take my word for it, though; I suggest consulting with one of the legal beagles that hangs around here first.
