That assumes that there exists some objective, mutually agreed-upon measure of "accuracy".
For example, Glenn Greenwald has said that there is no definition of what constitutes "terrorism" that is not inherently based on race[0]. This isn't saying that the measures we take to prevent "terrorism" are racist; it's saying that the actual pursuit - the goal itself - is inherently racist, albeit implicitly.
The argument in support of that claim is too long to go into here[1], but suffice to say that, if you believe that the word "terrorism" is simply a euphemism for rationalizing racist behaviour or suppressing legitimate political dissent, then no, you're not going to be happy when people find more accurate ways to target those individuals.
