Dear Senator Casey:
I just happened across your name on a list of supporters for PIPA today. I wanted to drop you a note to let you know that although I believe some kind of remedy is necessary for online pirating, I believe (like many others, especially those with a working knowledge of the technology) that the legislation as written is too heavy a regulatory hand. The processes laid out in PIPA are too likely to be abused to the detriment of free speech and open networks. The US should not be following behind such regimes as China and Syria for our network policy - that's just embarrassing.
Please work with the other members of the Congress to come up with a better bill.
