Hey, calm down. Let's not assign blame until we actually have some evidence. The one person arrested so far seems to have been a lone wolf with personal problems. Rather than running off in the directions of our favorite prejudice, let's find out what is happening before we panic. The one good thing so far is that there have been incidents of vandalism and inconvenience but no injuries. That may mean that law enforcement has the time to find out what's going on and provide a measured response.
