a) violence is committed by people. so: get rid of all people b)
   violence is committed by some people: so, remove some people. c)
   getting rid of people is wrong. So, change the violent acts. d)
   how do you change the violent acts? You can stop them as they
   happen by monitoring actions and preventing as they occur. e)
   But as they happen isn't soon enough? Then you stop them before
   they start. f) But how do you stop people from committing
   violence before they do it? h) What do they commit violence
   with? Remove the tools they use. i) What tools are used for
   violence? guns? bombs? Can you remove them? j) You can make
   laws. But not everybody follow laws. k) You can restrict
   commerce. But not everybody follows commercial routes. l) So,
   you monitor everybody to make sure they don't have tools for
   violence. m) But what about making their own? Can you restrict
   parts? n) Violent tools follow the laws of physics. Can you
   restrict the laws of physics if someone builds a weapon out of
   fertilizer, ammonia and a box of nails? o) So, while perhaps
   some help, gun control can't fully solve violent acts. This
   doesn't mean it's not valuable but it's not a total solution. p)
   So we'll continue: If you can't restrict the tools used... maybe
   you can stop the people from getting to the areas you are
   protecting. q) Ok, you close the borders. But what if they're
   already inside? r) You monitor everybody. But for what? What can
   you monitor them for? == Quite true. Back in the 1980s, when
   terrorism was usually cubans stealing a plane and demanding
   ransom or something, head scarves were banned in my mother's
   workplace. She worked for the local government in their justice
   system. No native Muslims complained. That was just how it was.
   Government office. Separations of church + state and such. A
   couple of American black muslims did but this was an era of
   racial quotas for hiring. Affirmitive action has improved
   GREATLY since then, but it was in its raw form then. The thing
   is: They ALSO banned Jewish headgear. Lots of Lawyers were
   jewish. In short, outside of a few rabble-rousers, nobody
   complained about the restriction. But France? I don't know if
   they restricted all religious displays on heads or just the
   scarves. But if it was just the scarves? Yeah, that's pretty
   bad.
