bomb sniffing dogs? might be able to smell gunpowder.

Two years ago, the DC subway announced that they would search bags randomly at entrances into the system, but they never implemented it. Friday they announced they were going to implement it immediately.

If you use public transport now, the courts have ruled that the Bill of Rights doesn't apply to you. You are "opting in" to the searches by entering the system. I wonder when they will extend that to anyone who uses public roads?

Usually they just are sniffing for drugs or explosives. Guns would not rate. But the perp who doesn't know that would most likely get pretty nervous at the site of a few police dogs.

Is there explicit state law that says you cannot legally carry on public transportation? I would imagine it would be a state law.

Well now they all know.

At least those who read the Cellar.

Beats me. You are thinking about the 2nd Amendment, and I'm thinking about the 4th. I don't think they care much about guns specifically. They will be doing swab tests looking for explosive residue, and detaining you for the 5 minutes or so for the reaction on the swab to take place. And then searching your bag if it's positive. If you decline to be searched, they will detain you and question you for a while. Then you will be kicked out of the system for that day.

This isn't an airport, it's just people going about their daily routine.

But it's random. Random stations, and random passengers.

Sounds obstructive to freedom to move about.
