6. Resolved, That the recent unmanly and murderous assaults which have disgraced the national capital, are but the single outbursts of that fierce spirit of determined domination which has revealed itself so fully on a larger field, and which manifests itself at every point of contact between freedom and slavery, and which, if it shall not be promptly met and subdued, will render any free expression of opinion, any independence of personal action by prominent men of the free States in relation to the great national issue now pending, imprudent and perilous, unless it shall be understood that it is to be backed up by the bowie-knife and the revolver.
