Around here, traffic issues around schools at certain hours have gotten much worse since the Covid thing. I think many of the kids who used to ride the bus have been held back from doing so by their parents. Who choose to personally drive them to school now. Which results in a lot more congestion than pre-Covid.Schools have a massive problem managing pedestrian and vehicle traffic daily...and then throw in WhoHoo Flu protocols for the past two years.
Having extraneous people mobbed around schools can't be a good thing. From what I've seen on cable TV news coverage, the shooting sites are soon mobbed with anxious parents, news crews and assorted looky-loos. Might be a good thing to close off the area by several blocks ASAP. And after some point, probably too many "first" responders.
