See, on TV and in the movies (Enemy of the State, anyone), the government always has whatever technology they need at exactly the right moment they need it to solve a problem. Even more, they have unlimited budgets to pursue every case.
So of course people think Malaysia 370 was under total observation all the time. It’s the only story that “makes sense” given what they all “know.”
The ‘CSI effect’ also causes huge problems at jury trials these days, with jurors often unable to believe that a CSI-style analysis of evidence isn’t possible or hasn’t been done. Equally pernicious, CSI-based evidence is often held in higher regard, now, that previously on the basis that it must be accurate. Because, you know, unless you’re dealing with the master-villian of the series the CSI analyses are likely to have successfully drawn conclusions.
Yay TV and technology?
