I'm in several pages now and don't see a single number of double digit injuries let alone a dozen or multiple dozens.
Several of the ones I've clicked through to the source on seem to be counting people injured in things other than the shooting (e.g. brawl injures X, dude draws gun, shoots one person = 1 dead, X injuries).
The fact that they call the page "Mass Shootings in 2019" when even they say in their about-us[0] that they attempt to catalog each and every shooting seems to indicate a bias (to put it mildly). Edit: actually I'm wrong, I was only looking at the "Mass shootings" portion of their data. Their definition of "mass" seems to be "4+ people injured and/or killed including people not injured/killed" which seems slimy considering how they seem to be counting injuries. That said, they seem to be a pretty damn good source for raw information and generally unbiased with their numbers.
Edit: got through all the 2019 results (couldn't get CSV export to work with my browser) and found exactly two results for a dozen.
One event[1] has 6 dead, 6 injured but the source doesn't mention any of the people injured other than the 5 victims and one gunman who died, maybe an error in the data?
The other event is the Virginia Beach shooting.
In any case I think it's safe to conclude that events where a dozen people get shot happen less than monthly.
According to the source, the shootings on the following days have 9 or more injuries or deaths in 2019: Jan 15 (12), May 7 (9), May 18 (9), May 25 (9 and 10), May 31 (13).
So obviously I was wrong that people were killing DOZENS every month. It is more like mass shootings involving 9 or more people are happening ONCE PER MONTH on average.
