Personal security in the context of "Civil liberty"

Civil liberties are fundamental rights and freedoms that governments pledge not to restrict, either through constitutions, legislation, or judicial interpretation, without due process of law. Although the scope of civil liberties differs between countries, they often include the freedom of conscience, freedom of the press, freedom of religion, freedom of expression, freedom of assembly, personal security, personal liberty, freedom of speech, right to privacy, equality before the law, due process of law, the right to a fair trial, and the right to life. Other civil liberties include the right to own property, the right to defend oneself, and the right to bodily integrity. Within the distinctions between civil liberties and other types of liberty, distinctions exist between positive liberty/positive rights and negative liberty/negative rights.

Libertarians advocate for the negative liberty aspect of civil liberties, emphasizing minimal government intervention in both personal and economic affairs. Influential advocates of this interpretation include John Stuart Mill, whose work On Liberty argues for the protection of individual freedoms from government encroachment, and Friedrich Hayek, whose The Road to Serfdom warns against the dangers of expanding state power. Ayn Rand's Atlas Shrugged and Ron Paul's The Revolution: A Manifesto further emphasize the importance of safeguarding personal autonomy and limiting government authority. These contributions have played a significant role in shaping the discourse on civil liberties and the appropriate scope of government.

A security detail, often known as a PSD (protective services detail, personal security detachment, personal security detail) or PPD (personal protection detail), is a protective team assigned to protect the personal security of an individual or group. PSDs can consist of multiple federal and state government organisations, military personnel, law enforcement agents and/or private security contractors or private military contractors.
