General Discussion

As has been stated, many recruits have not passed a pre-employment drug screen. Or they may cheat it by submitting some clean urine belonging to someone else. So how many ICE and CBP agents might there be who are going to work impaired? And once they are hired, they have easy access to all kinds of dope which they can seize and fail to report. It's too late now to conduct a drug screen on Ms. Good's killer immediately after he shot her. For all we know he may have been amped up on something which made him more aggressive than the usual "badge-heavy" guy on the beat.
BTW, it's a good thing that the Minnesota authorities have custody of Good's body. At this point it's not hard to imagine that the Feds may have tried to fake the toxicology part of her autopsy to say she had drugs in her body so they can continue their victim-blaming campaign to try to exonerate her killer.
