X, Y and Z have all been retrenched by the mining company for which they worked. They have been looking for jobs for six months without success. They bear grudge against the government because they have lost their jobs. They are of the view that the government does not properly enforce immigration laws, that millions of people enter the country illegally and that the citizens of the country are unemployed because these illegal immigrants are employed by the mines because they are prepared to work for very law salaries. X, Y and Z feel that the government ought to be encouraged to deport all illegal immigrants. They decide that this can only be achieved by violent means. They plan an attack on a certain neighbourhood which they know is inhabited by illegal immigrants. In the early hours of the morning, they set alight the homes of the people. Many are injured and some die as a result of the attack. Explain whether X, Y and Z can be charged with the crime of terrorism?
