Precedent for Warrantless Net Monitoring Set

    So law enforcement can just sit with a packet filter scanning for the word "drugs"? That's just absurd. If law enforcement has reason to believe that an individual is committing illegal acts, they can go and get a warrant. Thanks to FISA, that's not the most difficult task. However, this isn't like a drug deal on a street corner; this is more analagous to being able to tap everybody's cell phone, hoping to find one or two people selling drugs.

      There is also frequently a connection to drug use, thus the fact that the vehicle was speeding is automatically sufficient cause to search a vehicle for drugs, even if only to add the potential for DWI charges.

      Nope.

      The controlling legal authority is the Fourth/Fourteenth Amendment, mandating freedom from unreasonable search. This is best viewed in the light of Katz v. United States, in which the Nine Worthies declared that searches into any area required justification, when a person had a reasonable expectation of privacy.

      Your car isn't the same as your home, with the same protection. It is, however, more private than not. A search by a police officer may not require a warrant, but it does require some sort of legal justification, such as probable cause (facts and circumstances which would lead a reasonable officer to believe that evidence of a crime is present)

      Speeding is evidence of speeding. It could possibly be evidence of drug/alcohol impairment, depending upon what else is going on. It could be a piece of circumstantial evidence for any number of things. It does not, however, automatically justify a search.

      And I never charge DUI/DUID off of a vehicle search. I charge DUI/DUID off of my observations of the driver's manual dexterity and ability to focus and concentrate, and my observations of the vehicle in motion, and the alcohol/drug test justified by said observations. The mere presence of drugs does not imply the consumption of said drugs strongly enough to charge DUI, absent other evidence.

    • If you are an individual with less than 5 grams of cannabis (hash/weed), police will ignore you.
    • You can grow your own plants for your personal use (maximum 5 plants, no technical aids such as lamps... otherwise everything will be impounded and you're fair game for prosecution).
    • You can open an establishment for selling cannabis, provided you abide with a whole number of regulations (including: no commercials, no admittance to minors, no selling of alcoholic beverages -- hence the name "coffeeshop", no selling of harddrugs, no selling of more than 5 grams per transaction, no total stock of more than 500 grams).

    Police can still decide to prosecute for any of the above if it's causing problems in any kind of way (i.e.: you're stealing to get drugs, the clients of a coffeeshop are wrecking the street, ...)
