Question

In Mapp v. Ohio, what was one objection of the ACLU to Mapp's arrest?

Answer 1

Mapp v ohio - convictions cannot be based on evidence from an illegal search
Horton v california - officers can gather evidence that is in plain view
Terry v ohio - officers can legally carry out a stop and frisk

Answer 2

The ruling in Weeks, however, was limited to the federal government. That changed with the Supreme Court's landmark 1961 decision in Mapp v. Ohio. ... In 1961, citing the ACLU's arguments, the Supreme Court reversed Mapp's conviction and adopted the exclusionary rule as a national standard.
