From the NYT:
He was born on Dec. 25, 1964, in Kent, in southeastern England, and recently lived near Birmingham, historically known for its automotive industry and now home to many South Asian and Caribbean immigrants and their children. It was there, in the Spring Hill neighborhood, that Mr. Masood rented from an Enterprise branch the Hyundai Tucson that he used in the attack.But he wasn’t an immigrant, much less a refugee, so what are you moronic Trump voters worrying about?
Mr. Masood had a record of convictions, stretching from 1983 to 2003, for assault, weapons possession and violations of public order. But he was not the subject of any current investigation, and “there was no prior intelligence about his intent to mount a terrorist attack,” the London police said.
Granted, logically, these cases suggest that the problems stemming from immigration aren’t short term, that they can well manifest themselves more than a half century after this guy’s parents immigrated. So, reason would suggest that we need to be a lot more prudent about who we let in in the near future because immigration could still be causing problems for our great-grandchildren in the distant future.
