You know, I actually am having trouble being sympathetic to people who can forget they have a firearm in their purse.
I think the fines are fitting punishment. No jail time is deserved for stuff like this.
That said, I do not agree that it should be illegal to carry in a federal courthouse, but this is not exactly a modern or secret law here, especially since they submitted to having their purses go through the scanner, after no doubt passing numerous signs.
Seriously, did they really "forget" they had guns? At what point during an assault/rape/murder would they remember?
