This is what needs to be done. The problem is I don't know how to be successful getting this types of laws passed:
We need to make it so that the government cannot request the data without a court order. The court order should be required to be put into public record within 48 hours of the data transfer. This gives the government enough time to deal with time sensitive arrests while preventing abuse since their actions will shortly be revealed to the public. We need to them make it illegal for corporations to share the data with the government without a aforementioned court order. All employees in charge of gathering the data must see the court order before sharing the data. Breaking these laws should cause all involved, both government officials and corporate employees/managers, to be arrested pending a trial and all data gathered to be useless for prosecution.
1. Incorrect, so long as it kills less people it will be fine.
While I would hope this is true, I would find it more likely that the news media would play the deaths up for their own gain and cause masses to have unfavorable opinions of the technology. A four year old dieing in a firey blaze because of something that the majority would probably already by distrustful of likely cause the technology to be banned or highly contrained, statistics be damned.
