Someone on Nextdoor was asking this question, and I was tempted to respond that the only thing HOAs collect is money. The real responses to the question ranged from, "It depends on your HOA" to "That's not part of what an HOA does." While I can understand that crime is separate from house paint and green lawns, since crime is the #1 factor in property values, HOAs probably need to DO something when it comes to crime.
