Serials are well made.
Dramatisation would seem unnecessary, but nevertheless they show the pain of the victim and thus move the viewer not to support crimes.
Actors should be inter changed in their roles now and then, because the accused is always portrayed by similar set of persons and so, most of the viewers guess the criminal as one these.
The charm of crime serials rest in the "whodunnit" thing and that should remain intact.
Showing only murder cases is bit boring and please show other crimes like chit fund cheating, MLM cheating and confidence trickery so that "Crime patrol" can claim that it has awareness content. Also show how Child trafficking and Flesh trade can be prevented.
