What government officials call "paid administrative leave" most of us know as a vacation. Hopefully he gets put on permanent unpaid administrative leave, also know as being fired.
It's SOP. Innocent until proven guilty. Frankly I would prefer to pay him NOT to teach my kids. He's less dangerous to our kids when he's on paid leave.
If he did what we all think he did, then he won't be on "paid" leave for long.
