The topic of police officer suicides are still in the news

Sadly, the topic of police officer suicides are still in the news. Please review the attached articles. They are quite accurate and powerful! Afterwards, please answer the following two questions.

1. Why does it seem that police suicides seem to be rising; especially in the CPD?

2. What realistic steps can police and security departments make to help officers deal with the stresses of policing and PTSD?

I expect at least 1+ page of information per question.
