State of Authority
Towers are symbols for State power, built on fear, rule and regulation, used to contain those who pose a threat to security. Actions taken whether agreeable or not are usually hidden under the umbrella of national security. If an individual is caught "between the cracks" isolation from the sovereign state usually ensues. This happens frequently especially during conflicts leaving the individual powerless, isolated and stateless with no recourse to the rule of law.
A state of "Bare Life" becomes the norm for the isolated and the hidden censored security net for society.
