"Suggesting they will remove human rights is clearly a way to loose the next election, they must see that?"
Alas, no. The government (of any flabour or stripe) has been weaving a narrative, supported by certain elements of the press, that Human Rights only serves to protect criminals who would otherwise have been convicted. It's on this platform that the right (ConKip) has been steadily building public concensus towards getting out of the EU.
Once we leave the EU (which is looking fairly inevitable at the moment) we will lose not just the HR protections we have, but *all* oversight that prevents our government from enacting just about any measure they want.
For some examples of things the EU, ECHR and ECJ have protected us from look back over the last four or five Home Secretaries careers and look at the various plans that have been scuppered by Europe saying "Non!" and "Nein!" at our leaders; Identity Cards, Stop & Search, Centralised DNA database, Camera surveillance in homes (Yes, they did try that one) and many others.
Unfortunately, the stupid part of our nations population has come to believe that to get rid of the TerrorPedos, Brown People Next Door and Spongers(tm), we have to give up this oversight...but it's all ok, because Cameron will write a nice, new British Charter that will protect all the "Proper Brits", won't he?
Please, when the referendum comes up, consider this before voting away our last line of defence.
