Out of curiosity, do you think people should be jailed for every time they are found guilty of racism? and should the police prosecute racists? should the law change as at the moment, my understanding is that, it is not illegal to be racist. Because at the moment you seem saying that people who falsely accuse other people of something that is not illegal in the first place should be locked up in jail.
If on the other hand, you simply meant that people who commit perjury should always be jailed that is a very thing to what is in the your OP.
Using last-in first-out as redundancy selection policy can be discriminatory on grounds of age, gender and race as women, young people and ethnic minorities, tend, in general, to have shorter length of service than white, male middle-aged workers. That is why most employment advisors recommend that employers do not apply last-in first- out and use objective selection criteria based on the employee's ability to do their job.
