Rhys had plenty of knowledge about the cop force before even joining S.R.T, S.R.T didn't help him nor any other SP members. Rhys was put in S.R.T because he knew how to do things others didn't, he is good at the game.
When Rhys was in S.R.T, they didn't associate with GD, therefore only 'gaining' knowledge of S.R.T? Which at the time would've been full of SP members anyway?
Think about it though, how many people go from rebel gangs to cop/srt. Look @ the current roster,
Lucas - SP.
Surey - Leader of NTR
Aaron - Been in and out of NTR
Augnov - No gang?
Jay - SP (started cop, but went SP with Rhys)
Cables - NTR
Apollo - NTR
In conclusion, I feel like this post is pointless.
