Most of my childhood neighbourhood drama involved wildlife - usually bears or cougars - wandering into town. Kids would stay to main roads and off our woodland shortcuts for a couple of weeks, but it was no big deal.
The scariest thing happened one summer when I was working at a small military post. This was a training base had a small full time staff and saw a lot of trainees in the spring and summer.
On the day in question, I was supposed to be the Duty Officer (ie - the responsible party) for the day. For whatever reason, I'd swapped out with one of my roomies.
I was hanging out and one of the soldiers came up to me and said "Ma'am, I need to show you something."
Took me into the men's room and I was expecting a maintenance problem or something.
He took the lid off the back of the toilet tank and showed me a bomb.
Now, I don't know much about bombs, but it had batteries, and wires, and a container of an unknown, coloured liquid. Given all that, I went with "bomb."
Went back to my roomie and said "Lee, there's a bomb in the men's bathroom." It took several tries, but eventually she believed me.
We evacuated the buildings.
She called the police.
They called their bomb team.
The bomb team consulted the military bomb squad.
All this took forever because the main military base was an hour away, as was the police bomb squad.
Eventually, all the experts agreed that yep, it sure looked like a bomb.
Now, in the middle of all this, people were saying "Uh...that's a prop left over from some training we did last week. We were supposed to do leadership exercises and one of them was to command a team doing a search for a bomb. We forgot to put the prop away."
Unfortunately, they had to treat it as real.
And since they couldn't move it, the decision was made to "blow it in place", ie set a small charge on it and detonate it.
They put up shields around the stall and...blew up the toilet. The object was destroyed and did not explode.
Since it was now the middle of the night and the building was still full of assorted bomb-people, there was a whole training camp of people who could not get back to our rooms.
So they sent us across the road to the government's underground emergency nuclear bunker and we spent the night deep underground in small concrete cubicles.
The only sigificant falll out that I can recall was my poor roomie. It seems that in all the confusion she'd forgotten to call the Base Commander at home and tell him that people were blowing up his buildings...he was a little testy about that.
