There are two options:

Consent - 'Co-operate'

Don't consent - 'Resist'

Both options are viable in preserving your freedom, depending the precautions you take.

Iris is correct when he emphatically quotes Berry Cooper. By not consenting, this throws out a huge red flag, the radio lights up with calls of "We have a refusal' The cursury search can usually be beat if the hiding spot if good enough. The only negative, is that if he does find it, you consented, you're arrested, can't contest it in court with a motion to suppress.

It's quite satisfying not consenting in my opinion. Standing up for your rights. You don't fall prey of their mind games and their domination and power. This is the anarchist way. So, if you don't want to consent, be aware they may call a K9 unit. Therefore, wrap you cannabis while wearing gloves, do this before you leave in a new baggy, so it doesn't have time to permeate. Put it in the middle of the vehile, possible high up so the dog can't smell it. Better safe then sorry.
