How does this work ?
Okay, I get that he didn't kill anyone, but he attempted blackmail on a grand scale. He threatened (baselessly as it turns out) tens of thousands of possible victims to extort money.
Again, he didn't kill anyone, but that level of threat, to me, means he should have gone to prison for six months, not just have an electronic curfew.
The sentence seems a bit light, in other words. I guess the judge found him to not be that much of a threat after all. Either that or he's setting the guy up for a major sentence next time around.
