I've just witnessed a crime from my bedroom window

I've just witnessed a crime from my bedroom window, but I do not know how I can help that poor woman. I was at my PC when I heard this woman scream "come back, he just stole my bag". I looked down from my 17th floor & saw a plump woman desparately running after a man. The guy's much faster as he dashed across the carpark & away from my sight. It's dark & I can't even make out their features & race, but I can see he's in dark tee & pants.

I woke my husband & he didn't know what to do too. I was deliberating if I should call the police, but stopped short cos I do not know if that can help, & how I can help. I feel so totally helpless. Now, I'm sitting here writing this cos it's the only way I know how to deal with this. I am very disturbed. I live in a pretty good neighbourhood (not swanky, but decent), & yet such a bold crime had taken place right before my eyes. I feel paranoid now. Am totally taken out of my comfort zone. My home is not safe!!! That woman could have been me. Just last Fri, I was out with the gals & got home about midnight too.

Should I not wear my jewellry, watch, etc out of my home? Should I only have say $10 in my wallet. Are my boys in any danger if I were to bring them out? I think from now on, if I get home late, I'll get Andy to meet me downstairs & to escort me up home. I'll feel much safer with him around.

I am very disturbed, & my sympathy & apologies go out to that woman victim I saw desparately running after her robber. The trees were partially blocking my view, but I do hope someone on the ground level heard her & gave chase.
