Here’s a case where a man got shot for reaching for his phone, the officer involved thought it was a gun.
“Hold on sir, don’t unlock that. There have been reports of people triggering explosives with their phones. Hand it to me and give me your passcode.”
This is easy as fuck. I could come up with 10 bullshit excuses to make you unlock your phone in as many minutes.
Don’t give cops a reason to take your phone. Your recording is likely your only protection.
