I am wondering why you can say "I robbed a bank and stole the money..." or "I robbed a post office..." or "The bus was robbed while the passengers were at the restaurant"
But it sounds extremely strange to say:
"Last night, my car was robbed and they took my stereo, my money and all of my CDs."
The more common way to express that would be my car was broken into but why can't you say my car was robbed or my purse was robbed"?
