Right now, like or hate it, this act, as well abortion are conctitutional. If we insist on our own interpretation of the Constitution, we abandon one of our strongest points, the need to elect those who would ammend the Constitution to make these act illegal.
If we insist on our own result-less read on the COnstitution, all we do is pi** in the wind. If we accept the legality, (but moral unaceptability) of the current read, then maybe enough people get angry enough to elect the right people to change it.
The Constitution doesn't need to be amended. Asset forfeiture laws are already illegal. In the past, politicians and judges were able to ignore citizens. Things are changing with advancements in communications in the mix. We can communicate with each other directly, and have a forum where tens of thousands of minds can meet to dissect legislation and the media's spin.
I grew up in the 50's and 60's and the difference in our access to each other through internet communication now, compared with what we had access to then is astounding. Given a few more years, unless politicians manage to shut down the internet, the political class will have to start to fear for their jobs. That's how things will change, I think.
