Sorry to read that, but it's still a statistically small percent that happens to. One can say "but even one is too much", and I appreciate the sentiment, but optimizing for the .1% isn't always a good path.

"they" probably contributed to the culture that produced the current school paraprofessionals.
EDIT: Some interesting numbers at https://www.missingkids.org/theissues/nonfamily - of abductions reported to them, 1% are by non-family members, meaning... 99% of reported cases (to their org) are by family members. That may not line up with 'law enforcement' numbers exactly - there's not a clear indication as to what gets reported to them. But the ~1% matches up with other numbers I've seen in the past on missing children. It's almost always a family member or someone known to the child.
