Sometimes it is Not someone's choice to be homeless.  The reason the social workers are with  the police is because they have more training in assessment of the persons condition, this could be a case of anything such as someone with Alzheimer's not knowing where they are, Vets with PTSD, mentally ill people who for reasons beyond their control have been off their medication which is dangerous and dozens of other situations other than just being "a dirty lazy drunk" which is how many people, including policemen, may see them as. Have some compassion, you never know what some of these people have been through and adding a Social Worker would be an asset. Honestly, reading some of these opinions show some people have zero empathy, which is disturbing since that is the definition of a sociopath.
