I’ve been asked to speculate on the type of weapon used by the Highland Park shooter. I’ve heard audio of the shooting, but beyond commenting that it was likely some sort of repeating firearm, I’ve got nothing else to say. The type of weapon will eventually be identified.
I’ve seen an unsubstantiated report that a “high powered” rifle has been recovered. Perhaps one was. I’m content to wait for the police or prosecutors working the case to identify the weapon when it suits the progress of their investigation.
