I will concede that the handling of that specific event was stuffty. However, this was an isolated incident, NOT a systemic problem across Europe, which you'd know if you actually talked to anyone who lives there.
And by the way, 153 suspects does not mean 153 incidents. Multiple people can be suspects for the same crime.
Finally, you'll notice that most numbers in the article are preceded by the word "allegedly." So apparently a single incident that includes 22 alleged rapes, many of which police are doubtful about, means all migrants need to be removed. Got it.
