All anyone should be concerned about is how to kill or capture them.
Changing up your society to avoid terrorism - i.e. out of fear of terrorism - is inherently wrong, so there's no reason to speculate on how to better accommodate to such criminals.
If free and democratic society as it is radicalise them, then so be it. They pose much less of a threat than ordinary criminals anyway, just look up the general murder rates and compare them to terrorist related deaths; utterly insignificant in comparison.
