Even the stupid ones slip through! It takes one smart cell to repeat 9/11. The way you catch them is by targeted surveillance not by dragnet collection of information. The IC does this all the time,they do a powergrab make noise about it, achieve nothing and retain their power. Look at wmds in iraq,torturing,drone bombing,mass surveillance.
Theatrics to make it look like they are doing enough. Truth is, if someone immigrated or gets radicalized without detectio, the IC is relying on them not having good opsec. Spying on everyone (instead of with a warrant) , E2EE subversion,and these silly laws won't give them additional capacity when the actual terrorists and mass shooters that slip through already have bad opsec,don't use mainstream platforms or E2EE
