Any recent security experiences at MEX?

I'm going to Mexico City in a couple of weeks.

Safety issues aside, what is the airpot security situation like at Mexico City / Benito Juarez Airport? I'm curious in part because of the police officer shooting at the airport.

Is it questioning, bag inspection, re-questioning, random searches, everyone gets searched?

I know that they don't allow liquids purchased in the terminal to be brought on board, but that's the extent of my knowledge.

I'm accustomed to Argentina and Brazil, but I didn't know what it's like for Mexico City.

Thanks for letting me know.
