My neighbor just got mugged and I thought it worth sharing. This happened in broad daylight, around 11am. She was getting her keys out and a guy with a knife took her stuff and jumped in a van and sped off. Amazingly she managed to get the plates and car description. A delivery guy walking by had a phone and she immediately called the cops with the info, including which way they headed. The cops actually caught the guy(s) within about 20 minutes of her calling.
I remember this happening in another building years ago and the cops said those kinds of robberies usually came in spurts.
Remember to stay alert, and now is a great time to go make copies of everything in your wallet (easier to quickly call all the card companies) in case you loose it or it gets stolen.
