This guy is obviously not a terrorist, and certainly did not have any criminal intent whatsoever. Arrests are now a knee-jerk reaction among government lackeys as they are currently so easy to perform. No evidence is needed! If a citizen annoys you, (i.e. he points out the flaws in your useless, unnecessary, overpriced security device) you can just have him carted off by stormtroopers.
