Is Arlington Heights a dangerous neighbourhood?

I think technically I live adjacent to Arlington Heights but I go running along Venice and Crenshaw all the time and have never been hassled with anything more than the occasional annoying cat-call. More often people will shout friendly encouragements. There probably is a higher than average level of crime in the area and its not immaculately clean or anything but if you're just waiting for the bus on the corner you'll probably just be with working-class men and women commuting to/from work or families taking the bus down Venice to the beach. A homeless person might wander over talking to themself but they're not going to hurt you and they probably won't even ask you for money. I just wouldn't recommend waiting there by yourself after 10 pm.
