Subversion of the law to make it appear reasonable is wrong. I understand the probable clause, plain sight, etc.... This intrusion to apply a device unknown to me, without my permission is wrong. The fact that I've nothing to hide is immaterial.
I don't know how reasonable men can debate and misconstrue the document that allows them to debate, speek their minds freely and have the choice to formulate their own opinion and shout it to the world.
I've been the victim of illegal search, thankfully aquited of all charges. It SUCKS and sometimes the damage cannot be reversed.
