Is education sometimes a bad thing?

Sometimes, those people convicted of a road traffic offence are asked to retake their driving test. They have shown themselves to be irresponsible with their car and the state (notionally on our behalf) thinks it’s a good idea for them to be trained again in responsible use.

Sometimes, people misuse airguns. Some people think that it’s a good idea if these people are trained or re-trained in the correct use of these items and lectured in the importance of responsibility and safety.

Some people would agree with the first issue and not with the second. Why would that be?
