This story has already been discussed here a bit in comments, but it’s worth highlighting:
Once you’ve dehumanized drug offenders, it’s easy to steal their identities by Radley Balko
Consider what the federal government is arguing here. It’s arguing that if you’re arrested for a drug crime, including a crime unserious enough to merit a sentence of probation, the government retains the power to (a) steal your identity, (b) use that identity for drug policing, thus making your name and face known to potentially dangerous criminals, (c) interact with those criminals while posing as you, which could subject you to reprisals from those criminals, (d) expose photos of your family, including children, to those criminals, and (e) do all of this without your consent, and with no regard for your safety or public reputation.
The mindset that would allow government officials to not only engage in this sort of behavior, but to then fight in court to preserve their power to continue it is the same mindset that, for example, allows drug cops to compel juveniles and young women to become drug informants, with little regard for their safety — and to then make no apologies when those informants are murdered.
The list of atrocities and indignities routinely conducted in the name of the drug war is extraordinarily long.
The only true solution is to end it.
