I don't know if its true, but I hear there's a huge muslim neighborhood there that is pretty crazy. No laws basically, cops don't go there and shit. Not saying this is the religion of peace, but it probably is.
If you have Islamic refugees flooding into your country and those immigrants are bringing fully automatic rifles with them, you're going to have a bad time.
The more we kill them, the more that take their place. When someone is broke, starving, living in squalor, they're easily manipulated. They want someone to blame or believe in. That's how Hitler took power.
The thing is, the real issues won't be attacked. Radical Islamism will be singled out but not as much as people will make excuses for Islam in general as a peaceful religion, a hashtag on social media will sprout and the end result will be stronger islamic presence. These attacks will continue.
