In my youth we made tons of prank calls but 911 was not an option as it didn't start in Florida until the 90s. If it did, we probably would have done it too. Kids lack common sense and need a lot of direction.
While we didn't have 911, the police did have a phone number that *could* have been pranked. Gaining freedom to roam required that i memorize my home phone number, the police phone number and the fire department phone number.
However, even as a child we knew there was some lines that can't be crossed. Prank calling a business or friends we did all the time, but we would never even consider prank calling the police or fire department.
This was true of a lot of stuff. I did plenty of mildly stupid shit, but knew enough not to do really stupid shit. Thinking back any thing we did that we were smart enough to know required safety glasses was something we shouldn't have done at all.
I actually claim to have been a responsible juvenile delinquent. When I was 18 the drinking age had already been raised in my state, but the not in the neighboring state 70 miles away. We would drive to the other state, buy beer, put it in the trunk, drive home, drink in the woods and then walk home. We broke a shit ton of laws, including providing the beer to our even younger friends. So I was a juvenile delinquent. But we didn't drink and drive (unlike some other from the same town who would go the bars and then drive the 70 miles drunk or drink on the drive back) so a responsible one.
We did crap on our bikes in the woods that very much placed us at risk of broken bones, but we were always careful in the roads about cars.
