If it's a "necessary thing" in the military/LEO world, it's being instigated by the "old heads" who are invested in instilling the long term culture and values of the organization, and not by the young, dumb assholes who've been there a year or 3 and still think they have something to prove, right? Right??
I would venture a guess that it's no different than the college fraternity world. The sophomores, who were picked on last year, do all the hazing. The juniors hold the offices and od the work. The seniors are a little old for all this stuff, and just go to the parties.
