As to the schools, recently retired police personnel should fit the bill (depending on why they left).
The opportunity to respond to this is just too good to pass up...
As you know FF52, I had moved to and lived in Slave Lake for the lifestyle including playing on the water, fishing, hunting, etc, a while back... Until a little over a year and a half ago when I watched my house light up (one of the very first) along with over half the rest of town... Then I relocated...
But a few years back, a local RCMP officer went postal after a Mothers Day bash at the local Legion.... And he happened to live right across the street... Only funny because no one got hurt...
Seems like he took his 9mm service pistol and locked himself in the bathroom after being involved in an episode with other guests and also including his wife...
He fired one round, that went through the wall then through the wall to his attached garage, then through the outside garage wall above the garage door itself...
Upon further investigation, it was by methods (everything from strings and levels and then lasers) performed by K Division specialists deemed that the bullet had to have hit my house, probably around the garage door, or a bit above... An old work truck I kept for hauling was parked right in the driveway at that point in time, and it had a very large clump of Saskatoon bushes in the bed with the huge root ball at the back... I never thought much of it, and neither did they... There were no holes in my house, and there were no holes in my truck... The search took 3 days before they gave up...
Now, the plot thickens... On day 2 of that adventure, I had gone out and asked if it was ok if I took my truck around back to plant the Saskatoons and then left it elsewhere, yeah no problem, was the answer... Now the evening of the night after that (3rd day), after the investigating officers and detectives had given up and packed it in... I was in my office, having a few beers when I had a thought... It had been driving me batnavajo fry bread wondering how this elusive bullet could have been possibly defying all known laws of ballistics...
It just came to me, and I knew exactly where it was... It was a bit after 10:30 PM and I called a friend that had a metal detector and asked if I could borrow it... After he LHFO and pointed out that I always seemed to be scoffing while he scanned the beach, he asked why I wanted it... I said I would walk over (could not drive due to beer limit) and be there shortly... We both came back with it, and found a hot spot right beside a main bunch of the Saskatoon bushes in the root ball... I knew better than to disturb anything, and to rather just let the authorities do their job...
I then had no choice... I walked into the local establishment, went to the desk and raised my hands in the air... They looked perplexed... I knew some of them, and they knew that I knew some of their members quite well, a few being other neighbors that were cops... I continued to give them the straight face, and told them I was guilty... `Guilty of what?" they asked...
"Planting the evidence" I answered...
