Gang operations were a problem for me until then, but I think I've found the solution. A grenade does much more damage than a bullet, and if it doesn't solve all the problems, it has the merit of cleaning up the enemy ranks. Now I know what to do next time.
In the meantime, I have a tv game to win...
the first of the 'chaos on red light'
there are multiple crossroad on the map where NPC bring their car to die. Sometimes, NPC choose it's time for them too.
This one, near Saints HQ, is a special one. Everything can happen there.
