Shouting "Nuke!" In a Crowded Theatre
Two interesting takes on how to deal with threats. Folks at the University of Purdue want to equip every cell phone with a what is effectively a Geiger counter. Think of it as “security through ubiquity”. Meanwhile the NYPD wants to carefully restrict the distribution of Geiger counters and related devices because of fears of problems with false alarms and such.
Honestly, I think there is wisdom in both approaches. Probably the sanest thing is to have sensors everywhere and to learn not to overreact to false positives…. only people aren’t so good at that last part.
