Don't mass investigation would be justified if helped to prevent that number of deaths?
That's a very big 'if'. By all accounts mass surveillance and dragnet investigations don't work to find terrorists. Practically everything I've read on the subject (which admittedly isn't much) terrorists are stopped using information from more traditional investigatory methods like informants.
Giving the government the power to investigate 1.3 million citizens who oppose it is an extremely high price to pay in order save lives that might be taken by terrorists. Whether it's worth it isn't a question I can answer easily.
