The wording seems to indicate taking a specific action to delete specific things. So would having a browser/extension that automatically cleans up after itself imply guilt? Even people who don't do anything illegal, immoral, or unethical online might legitimately not want their computer constantly polluted with all the droppings from every site they visit - tracking cookies, cached ads, etc. What about browsing from a VM that loads a pristine provisioned image every time you boot it? Seems a reasonable way to avoid both that pollution and reduce likelihood of being infected by malware or other security issues. The responsible thing for any good patriotic law-abiding citizen to do. Either way, it would be a standard operating procedure. So anything that they didn't find would not be something that you had intentionally deleted.
