Of course the reality is those dangers while real are pretty rare. There’s always been some jerks out there (legends of poisoned/ trapped Halloween treats go back to the mid 60s) and there’s always going to be some jerks out there. But chances are you won’t encounter them. We’ve gotten pretty hyper paranoid, especially when it comes to kids, in the last few decades, but there really isn’t much evidence to back up that increased paranoia.
While there will be problems, there always are, on an individual kid basis they still have a better chance of winning the lottery than getting tampered Halloween treats.
I am sure you are right, but every Halloween there are warnings on nearly every TV station with “safety tips”. That is on local news (which I still watch) since I haven’t watched in years. Interesting side note, went to the grocery store yesterday evening (a little past 19:00 hrs.) in a small town of around 6.000 people and saw three houses that appeared to have “trick or treaters” and went by the local high school, heavy traffic and people parking, when “game night” is normally Friday night. Don’t know what was going on but thought I had missed a day for a moment.
