You’re missing a huge point here. You don’t have known, wanted felons “under surveillance.” You don’t follow them around, you arrest them. They have a warrant signed by a judge. You put them in cuffs, you don’t wait for them to commit more crime. People are throwing around terms here that do not apply.
Well how did that work out for them?
You say the cops don't conduct surveillance on wanted and or violent people? lol...
Another tid bit. How much back up did the marshals have to take down the perp yet what was it?? 5 other officers wounded?
