Of course there’s evidence of Islamic extremists using vehicles to kill people in public places. This isn’t even a secret, they have publicly taken responsibility for these attacks. The most recent being an attack in nyc. I agree that right now there isn’t evidence of this particular person being an Islamic terrorist, but it’s early days. It’s called speculation. The guy who was an Islamic extremist who did the nyc attack wasn’t Muslim. You can’t have a Christian last name and still be an Islamic extremist. I’m telling you, this isn’t a secret or something, they’ve done like 12 attack’s over the past 3 years that involved vehicles.
