91
Q

4 post-search exceptions to the fruit of the poisonous tree

93
Q

Passage of time (attenuation)

A

the more time between the violation and the obtaining of the evidence=more attenuation

94
Q

Length of the casual chain (attenuation)

A

the more intervening factors=more attenuation

95
Q

Intervening acts of free will (attenuation)

A

such as D’s voluntary decision to confess, consent to search, or a 3rd party being willing to testify

96
Q

flagrancy of police violation (attenuation)

A

if it is a technical, low level violation= more attenuation

97
Q

nature of 4th amend violation (attenuation)

A
