Don't really understand wor................

I found some thing that I do not understand:

‘They’ stopped people at the road side because they suspect something but ended up being kill because don’t know suspect on the car will have weapon……

‘They’ work in a team, but suddenly found they team mate died after fire fighting with the suspect…..because kena tembak by orang sendiri…..

‘They’ are legal in ‘collecting’ money ‘under the table’ but stopped a long from collecting the money in the public……

‘They’ are the protector…..but they are protecting……bad guys?

‘They’ suppose to be very brave……but always come after the incident ended?

You know who am I talking about? Haha, only clever people will know :P.
