Some examples that have been on these lists in the past:
- A school resource officers firearm that accidentally went off when a child hugged around his waist. No injuries (there are other questions, but doesn't qualify in the same way)
- An empty .22 casing found in a random school parking lot, probably fell out of a car or got caught in a boot or similar.
- A gang fight at 1am on a Saturday near to school property.
- My personal favorite: The two schools closest to me that showed up on one of the lists (Everytown, I believe?) because the police were dealing with an active robbery situation about 1/2 mi away and they asked the schools to go into lockdown. Apparently "lockdown" immediately and only ever means schools shooting.
- 2/3rd of school shootings that NPR couldn't verify happened.[1] [1] https://www.npr.org/sections/ed/2018/08/27/640323347/the-sch...
