Describe what "incidental" to the arrest means, drawing from Caslake and Cloutier.

  • Cloutier → “The restriction that the search must be “truly incidental” to the arrest means that the police must be attempting to achieve some valid purpose connected to the arrest”

  • Caslake → “The fact that this search was not, in the mind of the searching party, consistent with the proper purposes of search incident to arrest means that it falls outside the scope of this power”
