I’m not sure if you’ve ever been inserviced about problematic packages, but wires sticking out of one is a possible tip-off.
Stains on the package can be another, oil, some other possible chemicals.
A package sent from someone you don’t know can be another.
You should be highly suspicious of a package you aren’t expecting.
In the Limbaugh incident, it seems they pegged it as some sort of electronic device. Perhaps it was packaged sloppy with some wires exposed, and it being from someone he didn’t know, and he wasn’t expecting it, his security took the proper precautions.
There is a possibility that the events surrounding Breitbart may have caused Rush’s security to be elevated. I’m not sure that is the case.
This may have taken place today as a coincidence. It’s also possible you are right.
Remember that Rush’s security undoubtedly checks the mail at some location away from Rush, before it is handed to him.
Perhaps they were paranoid. Who knows.
