And now we see that person has been released and is "no longer a suspect in this crime". In fact, he "has no connection with this crime", according to various police statements.
I wonder who they are looking for now?
I expect this incident was almost certainly a political assassination, probably by a deranged Leftist or Muslim, encouraged by a larger community of like-minded people.
We have seen this movie before.
If police think it must be a muslim then, of course, they have to arrest a white guy to keep their immigrant narrative with a positive slant.
