Tunick’s federal public defenders,
TBH I hope he can get more than public defenders. They work hard but they are often over worked and under resourced. Plus not being specialists in this. Maybe the EFF will offer specialist help. EFF is already aware of his case. Hence why anyone who is able to, should donate to the EFF. So they can employ high powered lawyers.
Additionally, the agents produced no warrant and did not read Tunick his rights.
NAL, but I think the gov can't have it both ways. IF they did not produce a warrant or Mirandize him, THEN they cannot come at him for wiping his own phone. The gov might have a case if they had a warrant and he knowingly wiped it. But that's not what allegedly happened here. No warrant = still 100% his device to do what he wants.
Aside from his case, courts in the US are all over the place, on whether you can be compelled to unlock a device if there IS a warrant. More often than not, they have ruled you CAN'T be compelled to produce a passcode from your memory. But in some cases, they have ruled the opposite. It's super chaotic, and prob needs a SCOTUS ruling.
