       Place

     Searches without a warrant

   Courts have recognized some situations
    when a search without a warrant can be
    legally conducted.
Search incident to lawful arrest

   Most common
   Lawfully arrested person and the area
    immediately surrounding the person
   Hidden weapons or evidence that might
    be destroyed.
              Stop and Frisk

   Reasonable belief that suspect is about to
    commit a crime and armed
   Police may stop and frisk for weapons

   Voluntarily agree.
   Once you consent to search you loose ALL
    RIGHT to challenge the evidence
   Usually only own property.
       Parent can consent to child’s property
       Roommate can consent to common areas
                     Plain View

   Object in plain view can be seized without
    a warrant.
   Police must be where they have a right to
       Ex. Marijuana plant sitting in living room
                Hot pursuit

   No need for warrant when police chase a
    suspect into a building.
         Emergency Situations

   Smell smoke, hear screams
   Police enter building to try to rescue
    someone and see illegal items in plain
     Border and airport searches

   Customs agents at border don’t need a
    warrant or probable cause.
   However searches must be random and
    searches that are “intrusive” require
    probable cause.
               Vehicle Searches

   Pretextual stops
       Generally illegal
       The police must first have a articulable reason
        to stop the car, and then have other suspicion
        to search following the stop.
       They must follow through with the first
        reason why they stopped you.
   Federal Law:
       Vehicle exception
       No requirement for a warrant

   Pennsylvania
       Greater protection from searches
       Warrantless searches require probable cause
        + other “emergency” situation
             Probable Cause

   Occupant committed a felony, or
   Vehicle used in the commission of a
    felony, or…
   Evidence of a crime concealed in vehicle,
   Accessible weapons in the vehicle.
       “Emergency Situations”

   Likely evidence will be driven away.
   Cannot secure scene while obtaining a
         Guidelines for Vehicle Consent
   Consent search
       Police must first return paperwork
       Tell person they are free to go
       Police can then ask if they can search
       The key is that the person being asked for
        consent cannot feel forced
