OK, follow me on this one. I'm in a basement doing a routine inspection of a furnace. In Pic #1,I'm looking up at a bullet hole the ceiling that came from the unit above me.
Pic #2 is the entrance hole of the bullet into the exhaust pipe of a furnace.
Pic #3 is the exit hole of the above exhaust pipe and another entrance hole into another exhaust pipe.
Conclusion: Furnaces around the country will be safer if we eliminate high capacity magazines.
