Motive ?

This las Vegas shooting is puzzling... I'm not going to speculate on a motive, in a knee jerk , jump to conclusions world, I will refrain...... I do think it's safe to say that this wasn't a case of a psycotic person going postal.... this was carefully planned out and executed over 3 days in the Mandalay.....he seems to have chosen this country music festival for a reason......he checked into the hotel with his girlfriend ID for some reason....he brought 11 suitcases into the room.... either all at once or over the course of several days......he set-up his guns and ammo in multiple rooms and windows in the suite.... probably going from gun to gun as the barrels got too hot to operate......we haven't heard anything from the media about this guy.....( By this time in the Dylan roof shooting we knew his life story, saw photos of his childhood and heard interviews with friends, family, teachers etc etc........but this POS paddock apparently had no social media footprint....no Facebook, twitter, or linekdin....we are told.....was he a registered voter ? No word yet.....his brother is a simpleton.....I saw an interview where he abruptly ended questioning because a reporter stepped on his flower bed......hmm....I hope today we learn more about motive.
