> No, I'm sorry. Kids being raped matters.
And I'm sorry, no
it doesn't matter to this argument. Civil liberties are civil liberties, whether we are talking about investigating the theft of a stick of chewing gum, the theft of millions of dollars, a slap in the face, the breaking of an arm, the rape of a child, or the murder to thousands of civilians by terrorists.
Bringing up the most horrible of crimes to justify a particular argument for increasing the powers of law enforcement is an obvious attempt to appeal to emotion, rather than to experience.
If your argument is any good, it will be just as good when talking about why the police should be able to search your phone for evidence of tax evasion as it is for talking about why the police should be able to search your phone for evidence of child rape and terrorism.
Otherwise, we go to a place where we say, "Well, the shouldn't summarily execute people who steal cigars from convenience stores, but when it comes to terrorists, we shouldn't let laws get in the way of their need to do what's expedient."
