Could the death and injury numbers have been lower with more aggressive police action, possibly. But they very likely could have been much higher.
A few words about pre-identification. It is hard to impossible. What we see after the horror of the event - colors how everything about identified shooter is seen and makes his quirks and anomalies stand-out. Before the event these factors are just too generalized.
Liberals & Progressives almost never blame the murderer (unless his being White can be blamed) but now seem keenly focused on firearms. Conservatives hold the shooter responsible but also search for biological-sociological-psychological traits as though the event could have been prevented with profiling. Or the shooter's right to bear arms denied.
What stands out after the murderer is known -- just has almost no predictive validity. Israel employs profiling on its airline but appears to rely on armed teachers in its schools.
