Report on wiretaps in 2015 suggests Americans are using less encryption to hide their activities online, is it really true? According to the report, not a single wiretap application was denied in 2015 for a total of 4,148 wiretaps. Of those wiretaps, only seven taps encountered encryption, down from twenty-two in 2014. The average cost of wiretaps increased an average 7 percent over 2014 pushing the cost to US$42,216 per tap. The FBI paid an unknown person or group at least US$1.3 million to break into the 5C iPhone of Syed Rizwan Farook, who murdered 14 people and wounded 22 others in 2015 in San Bernardino.”]
