There's nothing odd about that, seeing as how law enforcement and national defence are some the few tasks relegated to the state in a libertarian society. Now if you were talking about anarchists sporting such stickers you'd be right but libertarians are not anarchists. They want as little government as possible, not "no government at all". In other words, there is no incongruity in having both a Gadsen flag as well as some Thin Blue Line piece of marketing material on a truck.
