Subject: Re: Schumer's book tour postponed
How ironic.

And possibly pretextual. He wants good PR for his book tour, not bad PR - and he's staring down the prospect of lots of protests at his events. So better to delay for a while until tempers cool, and it's much more palatable to cite "security concerns" than "most of the people who might show up to his events are really mad at Schumer right now."
