When we talk about free speech from the perspective of homeland security, we are usually talking about how free speech is detrimental to the cause of homeland security. However, this is not necessarily true.
We will often feel that free speech harms our chances to keep our homeland secure. For example, in the current “war on terror,” the fact that we allow any sort of radical religious opinion to be expressed can seem to hurt us. Radical Muslims living in our own country can, if they wish, preach that it is proper to kill Americans. This would seem to make it harder for us to remain secure.
However, we can also argue that allowing freedom of speech makes us more secure. When we allow freedom of speech, we make our own citizens more committed to what our country stands for. We show that we truly believe in our core values. When we do this, we strengthen our country. We make our people more resilient and more resistant to what the terrorists are trying to do to us.
Thus, while there are ways in which the freedom of speech is detrimental to us, there are also ways in which it can help promote homeland security.
