Yes, but that article is talking about both public and privately owned cameras. You said public cameras. Unless you want the government to ban private CCTV the large number of private CCTV cameras in the UK isn't really much to do with the government.
Also that statistic on its own doesn't show that the UK has the highest rate unless you have number from other (similarly wealthy) countries to compare it to.
