The article mentions "arrested for a felony" not "convicted". Obviously these are very different things, and it shouldn't be too hard to see why some people have a problem with people found innocent still having their privacy invaded, not to mention the incentives it gives authorities to arrest more people. It almost encourages 'fishing' by arresting people with little to no evidence (or on unrelated charges) to get the DNA sample, and then releasing them without pressing charges. Groups that already feel targetted by the police might be wary of policies which give incentives for making questionable or spurious felony arrests in order to get data for investigations into future or previous crimes.
