We'd need to see how many ems violence related calls come in a year and the response of police to those.The 140 to 200 is data from VPD and Toronto (average of total employees used, officers are probably higher than the average). I cited the sources before. Based on discussions with people high in TPS and rural paramedics, there are not many officers working (especially at night, TPS is at ~two officers in many districts). The number of police working is like the Covid hospital problem. Things work well if you only need one or two concurrently, as soon as you need three (or N+1 more generally), it all goes to hell. Police budgets are ~20% of most property tax bills (Toronto, york, simcoe I have looked at before). So if you want more police out to push N+1 higher so you are less likely to bump into it (instead of hitting it almost every shift), you either need to increase the budget or reduce the cost per officer.
Then start asking why why why why why.
