Forcing the terrorists/criminals to roll their own encryption would be a huge win for both law enforcement/foreign intelligence agencies and the general public. When non-cryptographers write their encryption software the likelihood that it's insecure goes up, and if they're off using Mujahideen Secrets v5.0 instead of WhatsApp their communications would stick out like a sore thumb instead of blending in with regular users. When the terrorists/etc. don't blend in, the FBI/NSA/etc. don't have to sift through mainstream communications channels to figure out which people are bad guys and which are just regular people.
