Sort of like how retaliating against people who don't remain silent -- or who don't convey the mainstream lines in non-vulgar/non-pornographic ways -- may deter those people or others from exercising their rights to freedom of speech/expression (or silence/non-expression)? I have my doubt that it works out that way and deters much of anything; rather, it probably just polarizes and hardens prejudices with the same old practices continuing or getting amplified -- all without doing any real, sustainable good in stopping disruptors of better/calmer outcomes for all innocent persons.

That said, people who are sheep or are inclined to be sheep will take away the lesson that being a sheep makes it "easier". And people who are neither inclined to behave like sheep nor to be baited by sheep and/or wolves (even if they are baiting sheep and/or wolves to feel provoked)? Well, they will chart their own course undeterred -- all in the hopes of making it "better", whether it is easier or not, whether it is likely or not. This dynamic will continue at US border crossings/ports of entry, and I expect that little to nothing will change for the better because the country/countries has/have the popularly-deserved border control types.
