YES. 1: Any time I go through a border I have the expectation that an immigration officer (from any country) has access to my online activity. This could be a quick google search, but more likely I've been run through an automatic system to detect any red flags prior to arrival. A future government may see your actions now as 'unpatriotic'. 2: When we are not in our native countries (and even then) our rights are essentially 100% in the hands of the immigration officers whilst at a border. Read those immigration cards sometime. 3: In any country a Law Enforcement Officer can google you and can also use a 3rd party summary service to find out about you. So you you get arrested then anything you have online is available to be used as evidence against you. 4: When the rule of law applies, and decent people are enforcing the law, then none of this matters if you behave in a legal manner, even if you are fully exercising your right to free speech. However LEOs like the rest of us are human and have bias. So expect the worst at times. As we have seen recently a few bad actors can bring an entire force, state or even country into disrepute. 5: We should have the expectation that anything put into a computer, certainly written online or even said in a call can and probably is being captured. It's one of trillions of data points and ignored, but if you ever become famous, infamous or under suspicion then the data is there.
