I’m guessing someone who doesn’t know what really happened and assumed it was a bomb. You hear stuff like this on police scanners more often than you think and it turns out it wasn’t what the RP thought it was.
While it is possible it WAS a bomb, in light of other events this week, it is also possible he just made a false assumption. We will have to wait and see.
I agree...seems to early to be determining that it’s a bomb....let’s hope they were just speculating.
It takes a high explosive to initiate a low explosive like ammonium nitrate.
