Not one of the 59 or 500 were armed.   And the shooter was not licensed to own a full automatic weapon.   So the letters are totally useless.  The thought process is useless.   The thinking is to make a nation of sheep in pens just waiting for another shooter to break the law and kill them.   All the talk about this or that weapon does not matter a bit.  As demonstrated this time, police could not do anything.  And it took longer than a flight from LA to Vegas for them to find and break into the suite.  When they did it was over and the shooter had offed himself.   So the Police were of no value.  The bottom line is to carry as much defense as you can and shoot back.   Saw a photo of where a under-armed police officer hid behind a wall with his body cam focused on where the shots were coming from.   Had he been armed with an M-16, 30-06 or AK47 he could have been firing to keep the shooter's head down.  But he didn't.  Couldn't if he wanted to.  The letters are just bad thinking.
