June 24, 2015

Examples of Carrying a Dirk or Dagger

Dan was walking on a downtown Los Angeles street when he was approached by two LAPD police officers. According to the police, Dan looked suspicious so they detained him pending an investigation. As part of their investigation, one of the police officers began conducting a search of Dan’s clothing to see if he had any drugs or weapons. The officer’s search revealed Dan to be carrying a dagger in his back pocket. The police officers arrested Dan for carrying a concealed dagger. In this case, Dan’s criminal defense attorney would argue that the search of Dan’s pockets were in violation of his Fourth Amendment search and seizure rights. Moreover, the police had no reasonable suspicion to detain Dan in the first place because he was doing nothing wrong other than “looking suspicious” which is not objectively reasonable. Furthermore, the police officer searched Dan without any probable cause or reasonable suspicion that he may be carrying any weapons. If the court agrees to the unreasonableness of the detention and search of Dan’s pocket, then the dagger will be ordered suppressed and the prosecution will be unable to continue.

Dan was driving his car on a Los Angeles freeway when he was stopped by a police officer for speeding. The officer asked Dan if he could search Dan’s car for any drugs or weapons. Dan agreed that the officer could. A few minutes later, the police officer recovers a swiss-army knife in Dan’s center console. The officer pulls the blade out and discovers the knife’s blade exceeds the legal length. Dan is then arrested for carrying a dirk or dagger. In this case, Dan’s defense attorney would argue that the knife recovered from Dan’s vehicle does not comport with the statute. Particularly, the swiss-army knife is not a knife capable of “ready use,” in that it requires a person to use effort in manipulating the instrument to unlock the blade versus exposing the blade by a flick of the wrist or press of a button. Thus, Dan would not be guilty of this crime.
