Maybe, just maybe, this will start the process of dismantling the terrorism laws, but I'm not holding my breath.
This is why so many Americans want to keep the right to have weapons - at the end of the day, people have no means to protect themselves againt the government. I mean, the police and the army obey the government, not the population. So what is a people to do if its government unduly deprives it of its fundamental rights?
In my opinion, there's no better protection than for the government to know that it is surrounded by millions of armed citizens. For the government, aggressing the people would be like killing a cop in a police station. In theory anyway...
That reasoning may sound a little naive, but keep in mind that at the end of the day, we do rely on force (the police, the army) to protect ourselves against other citizens or against people from other countries, so relying on force to protect ourselves against a government is only a continuation of that reasoning.
