Thailand's lese majeste crackdown

Thailand's military junta is increasing its crackdown on those who insult the monarchy. The country's lese majeste laws are among the world's strictest, and criticising the royal family can be punishable by up to 15 years in prison. But critics say the junta is abusing the provision to silence their dissenters. What purpose does lese majeste serve, and how is it impacting free speech?
