Right and wrong are opinions, so you can say what your opinion is, but you can't say it like it is fact.
My opinion is that there are probably better ways to deal with the issue. Altering a persons mind would be much much trickier than for example reading someones, and knowing weather they will commit a crime and act on it.
Altering someones mind is not invasion of privacy, but is an infringment on ones right to choice.
There would be almost no way of knowing how to alter someones mind so that they didn't want to comit a crime. The altercation might also alter other parts of their personality. What makes us human is something closely defined, but something we haven't quite figured out. The slightest twitch would be like creating a new species, with strange morals and ideas.
In our society, it is good to find new ideas and think about them, only because we are mostly all think the same. Personally I think a human only does what is best for him. Even if one is doing someing "selfless" they are doing it to make them feel good, which is much different. If you created a race of humans that were truely selfless, they would die off like lemings for the benifit of others. It would be like self exploitation, instead of a slave master ruling the slaves, the slaves impose themselves on others.
I think a better way to go about this is to have everyone wear a brain-cap and have that transmit their thoughts to an anylizer which would determine weather the person is capable and actually wanting to perform a high crime. The machine would not record thoughts and would not disclose information unless a crime was committed. To further the idea of right to privacy, the machine could be set to not let any human see what it sees, thus making a persons privacy still theirs.
Only if a high crime was going to be committed would someone be alerted. The machine would disregard petty stealing and other small and insignificant crimes, but murder and other things like that would be seen as a threat. Of course this would only be in the ideal case that a computer could distinguish between a random thought and the actual will to kill....
