Ok, I've just heard a lot of what sounded like automatic weapons fire - a couple of pops, a delay, a few more, and then a whole lot at once - and looked out the window to see a convoy of police vans at a good rate of speed heading west up on Great Western Road here in Glasgow.
And, unless it is a major incident, I'll never know what's going on.
In the States I could have tuned into the police radio and followed it, but here they have police bands private.
I guess it could be fireworks. At 9:30 in the morning on a Tuesday? Or some unfortunate industrial accident a bit farther away? I wonder if there is a way to listen in on emergency services that I just don't know about?
