Seems like the government will go very hard on the guys involved with the riots last week. Talks on a political level to prosecute them for terrorism and cancelling Dutch citizenship. They will make a example out of those people, as said last week they were better of going for a 'normal' hooligan fight.
Terrorism I think they can get that, its about intend here. So if they can prove that they were out to strike fear in the jewish community, the odds of prosecuting them for terrorism are quite high.
Taking their passports away will be very difficult, and the government wouldnt win a lot with it. I even think it doesnt necesseraly mean those guys have to leave the country, it happened a dozen times here that they took such measures with people who joined ISIS. Also interesting that this got discussed in the Murica thread, now we have a live example here where you can see that its a practice that does exist here.
Safe to say that a bunch of people destroyed their future last week. The country is burning on a political level now.
