Sure, we all make Mc Steaks, but chances are, if she was keeping two purses in the car.. she didn't just, "forget them."
I have empathy for the people who are truely targets for no apparent reason, but people who leave GPS units, purses, CDs, stereos, or anything of apparent value in the car is just asking for a raping.

Edit.. PS- I do feel sorry for you, OP, because I know you'll pretty much be the one dealing with it.. but maybe your wife will learn a lesson?
