The thing I don't get is the woman in the second strip looking like a coworker, since Matt doesn't draw the strip himself. I suppose he could have given Ian a description, but even so it still doesn't quite make sense.

I understand people getting freaked by that sort of (even though in the first strip he's talking about getting a gun that would make it difficult to kill someone on accident) but firing plus a visit from the feds for joking about the experience? It would be nice to not live in a country that is apparently full of rabbits after every tragedy.

There's some more info about what happened here, including a link to an interview with Matt.
