SSERT

Today, while I was driving to my brother Mark's house - to borrow his generator - I saw an odd vehicle.

It looked a lot like an armored truck that moves money around. But it was painted green. And it had flashing lights and a siren like a police vehicle. It was going somewhere in a hurry. On its side were letters: SSERT

I guessed, correctly: South Suburban Emergency Response Team.

Here was the emergency:

A standoff in Oak Lawn between police and a man upset over losing power because of Friday's storms ended with the man arrested.

An armored vehicle was also on the scene, Graziadei said.

Even though you're without light
and cable and TV
and hot water and A/C
you oughtn't start a fight
with the S.S.E.R.T.!
