Obviously it isn't a lie but it's usually a gross exaggeration that's used to try and justify virtually any point of view. The word "disingenuous" was created specifically for that sort of argument.
For example the "drive home hammered" amplification. Recent changes in law regarding the "warn range", a blood alcohol level that has been shown through study in multiple jurisdictions to be statistically safe, now see people lose their license for days. The original intent of that law was to provide an actual warning and a detox period of 12 hours (longer than what should be required for alcohol to leave the system, at any rate), so that people wouldn't feel safe to push the limits of consumption.
Look at the laws that are being passed these days. Politicians have run out of reasonable measures to take, in their "law and order" campaigns. The result is a push to try and make the unreasonable seem reasonable, so that the electorate will continue to vote for them.
I had no idea that the idea of reckless driving causing harm to innocent individuals was such a gross exaggeration.
