Why to keep your distance...
When Apprehended, it does not matter when guilty or innocent:
The Police is part of the Prosecutor.
Its Job is to check You for any crimes committed.
You might think: well I will walk out within seconds
The problem with that is: you will always have done something
( possibly else than the charges ) wrong... everything within Criminal or Civil Law is more than 144.000 pages thick in some countries.
THEREFORE: ZIP IT.
ALWAYS Use your 5th Amendment rights!
No matter what people think of that.
They are Stupid if their advice contradicts the advice of this Lawyer...
