"The government has promised to lead a national debate on the gun laws with MPs debating the issue before the end of July."
Let us start with what the true Law of England actually is:
"In these several articles consist the rights, or, as they are frequently termed, the liberties of Englishmen: liberties more generally talked of, than thoroughly understood; and yet highly necessary to be perfectly known and considered by every man of rank and property, lest his ignorance of the points whereon they are founded should hurry him into faction and licentiousness on the one hand, or a pusillanimous indifference and criminal submission on the other. And we have seen that these rights consist, primarily, in the free enjoyment of personal security, of personal liberty, and of private property. So long as these remain inviolate, the subject is perfectly free; for every species of compulsive tyranny and oppression must act in opposition to one or other of these rights, having no other object upon which it can possibly be employed. To preserve these from violation, it is necessary that the constitution of parliament be supported in its full vigour; and limits, certainly known, be set to the royal prerogative. And, lastly, to vindicate these rights, when actually violated or attacked, the subjects of England are entitled, in the first place, to the regular administration and free course of justice in the courts of law; next, to the right of petitioning the king and parliament for redress of grievances; and, lastly, to the right of having and using arms for self-preservation and defence."
