Too small problems and are distraction from the major problems. Just recruit good officers in respective departments, they will do the job. "If you want to change a company, change its HR manager". Policing should be the job of police, not of the administrator.

"yeh jabro qahar nahi, ishq o masti ha" meaning, power can subdue but not transform. "jabro qahar sa mumkin nahi Jahan bani" one cannot run a government by force/fear.
