Yes, that is true. What I wanted to give you with my comment is an insight that this harsh sentence didn't come unexpectedly out of the blue.

Those girls have a long history of such "actions" and what in most civilized countries happens is that you first get fined, then you are maybe arrested and set free on probation, and if you still refuse to conform to a socially (and legally) more acceptable behaviour, you eventually end up in jail.

The same goes for Kasparov. He's been arrested so many times for willfully committing minor offenses, that if he is found to be guilty of biting that officer he'll probably get a sentence near the maximum of 5 years in prison.
