There are often unexpected roles within these areas that don't have you signing on with the primary organization most people expect. I don't know if they do it here, but in Toronto's main downtown courthouse, there is a Salvation Army office and the SA worker will come by the holding cell to collect phone numbers and messages to relay additional communication to loved ones and supports beyond the "one phone call". They often work harder to get a hold of people, make sure they actually say what you needed, relay a reply back, etc and in the past this has been absolutely vital for me in letting ppl know where the hell i am so they can show up and help get me bail. Also, since the cops always confiscate shoelaces and you get released with your shoes hanging open for a walk of shame home, the SA office has laces, coffew and clif bars for those leaving as well as referral help for shelters and so on. Not a service I wouldve guessed would exist in the criminal justice arena and not an area I thought I'd encounter SA in, but possibly the most useful thing SA has ever done for me personally.
