Cell Phone Surveillance Costs Can Change Privacy Protections
The United States Supreme Court has held that a person does have a reasonable expectation of privacy in their public movements. However, no specific rule has been announced as to when law enforcement surveillance violates this right. A Yale study found that the costs of surveillance can be as little as $.04 an hour. Decreasing costs of surveillance should trigger increased police surveillance under the Fourth Amendment otherwise there is too large of balance in favor of law enforcement over individual privacy rights.
