I think they did a great job limiting bias.

DEA Agent:"We are not the ones who make the laws, we are just here to enforce them." Any time i hear law enforcement employees sounding off with such garbage i ask; if you guys are just here to enforce the laws, why is it you do not pull over every person who goes even 1 mph over the speed limit. Watch their argument shift from "here to enforce" to "they are not the same"...
