Jim Kyle, D-Memphis, isn’t sure where the plan for the security upgrades at the Tennessee State Capitol and Legislative Plaza came from, or that they were altogether necessary. Kyle, the Senate minority leader,said he was under the impression the “renovations” that were approved for 2012 were for things like air conditioning and electrical upgrades. “[The security upgrade] may be the right thing to do, but I think it should have been more of an open, collective decision,” said Kyle. “Our constitution says ‘the doors of the Capitol shall remain open.'” He added that last year’s Occupy Wall Street protests likely prompted the efforts.
