I don’t know, just listening to the reports. I believe the knife person stabbed more than one person. I believe Borough Market was having a late shopping night today, so it’s conceivable that a lot of people are headed there.
Yeah I feel like I heard on the news that it wasn’t the armed anti terror unit who shot the guy, but police from the city of London (as in the borough, as in the financial district to the north side of the bridge). It’s conceivable that some police based in the City may carry guns, even if it’s not the norm for most boroughs. (Since It’s an obvious target for terror being a focal point of Western wealth and containing iconic landmarks like St. Paul’s. )
