Fourth, you hire a psychiatrist who really knows PTSD, and you give your investigation to them. Fifth, you take the truth and do what's right. And if you find it's a false claim and they lied, do us with PTSD a favor and criminally prosecute them. If you aren't having any luck with putting a plan in place, the best way to tell if you have a legitimate claim is to have someone do a legitimate investigation versus a whitewash, and use the same psychiatrist as described above. But think about all of this for a minute.
Many agencies require mandatory medicals after a certain age.
The nature of psychological problems and the attitudes in law enforcement about officers with these problems are keeping these type problems silent for the most part, until something happens. By then it's usually too late, the damage is done. A major concern for establishing such a plan, as I indicated above, is where the money and time will come from. Every agency in the United States is lawsuit conscious, occasionally to the point of paranoia. The biggest focus in law enforcement over the past 20 years has not been catching criminals.
