Sure, but that's orders of magnitude more effort, oversight, manpower and political risk involved than your typical "find a thousand people who have a paper trail saying they did X, pick the five hundred of those who you have an airtight case against, pick the hundred of those who juries will find least sympathetic, pick the 50 of those least likely to shoot back" type" operation that the fedcop enforcement agencies run fairly unilaterally every single day.
