FWIW as a Bristolian male...
I wrote to Kerry (not my MP or current colour of politics); this was the reply I received yesterday afternoon:
The way the press has chosen to report my comments on the Jo Yeates murder investigation has understandably caused a great deal of concern. I would like to make clear that I have not been leading calls for all men in Bristol to be DNA tested, and it would be wholly inappropriate for me to do so, as this is for the police to decide.
I was approached by the Express newspaper, and asked if I supported calls from Louise Smith's parents (a local woman who was murdered in 1995 and whose killer was traced after DNA testing) for such methods to be used in the Joanna Yeates case. My response was that I would support the police in DNA testing if the investigating officers considered that it would be a useful step in helping to identify Jo's killer.
Although much of the press speculation has specified men, perhaps unhelpfully, it would be for the police to decide who should be tested - male or female. I did, though, query whether it would be more productive to test beyond Clifton specifically, as only one of many practical and logistical considerations, if this option was pursued.
I am of course aware that people in Bristol would be concerned about the civil liberties aspects of DNA testing, and whether their records would be retained on the DNA database, so this would need to be looked at if the police do consider testing at some point. I also made clear that it could prove very difficult to test a significant proportion of the Bristol population, and that I am unclear how the police would actually go about it.
I hope you will be reassured that I have not "called" for testing, and nor have I in any way pre-empted what the police might do. I merely agreed that DNA testing has proved useful in solving crimes, but the police are best placed to decide whether it would be helpful in this instance.
