How did Americans see their natural rights as being infringed upon in the time before the Revolutionary War?

As we can see in the Declaration of Independence,
Americans believed they had certain inalienable natural rights.  They believed that they
had the right to be governed only if they consented to be governed.  They believed that
any government that ruled them had to protect their right to life, liberty, and
property.  The colonists believed that the British were infringing on three of these
four rights.

First, they believed the British were failing
to secure their consent to be governed.  The British did not let them have
representation in Parliament.  This, to the Americans, was a failure to obtain their
consent.

Second, they believed that the British infringed
on their liberty.  They felt that British practices like the use of vice-admiralty
courts constituted an infringment on people's liberty.  Finally, they believed the
British were violating the sanctity of their property.  This could be seen in such
British actions as quartering soldiers in private homes or in the issuance of writs of
assistance.

In these ways, the American colonists felt that
the British were violating their natural rights.
