I believe if people choose not to live their lives then they should be forced to keep living. In the long run, if people tried to commit suicide but it ended in suicide by police how is that making a difference besides giving someone leverage to deem police as cruel. It is their body, their life and their choice.
I believe it's the person choice to choose what they want to do since it is the right of freedom. If a person wants to commit suicide it is in their hands. It's the same as choosing what job the person wants to take like they choose. For example, a doctor or lawyer. So, it's the same as choosing to live or die.
