Unfortunately the bad ones always get the press, “bad teachers” aren’t that different from “bad cops”, the 99% who go in everyday and do a good job will never be seen on the news, the 1% who say and do stupid things will be televised for the whole word to see.
It’s rare for a week to go by now where I don’t see an article about an inappropriate relationship, a teacher caught on camera bragging about how they’re training kids (whether left or right), a teacher involved in a physical fight, a teacher arrested for (insert blank), a teacher talking crap about their students… it only takes 52 bad teachers (out of tens of thousands) but it’s enough to create a year of headlines.
