Of course, there are many examples of people of all races working together amicably and respectfully. However, there are also many examples of people being targeted, verbally and physically, because of their colour, both in the workplace and in public spaces. Many non-white people (and people being perceived as being "foreign") are reluctant to raise issues of discrimination for fear of being labelled "troublemakers", "over-sensitive", or of having a "chip on their shoulders". There is also the casual dismissal of discriminatory practices in recruitment and employment by invoking the offensive "playing the race card" accusation.
As to the protests and the lack of social distancing, it says how strongly people feel that they must demonstrate their outrage, hurt and solidarity, risking their own safety.
Let's face it, many people have ignored the rules for far more trivial reasons. And, when it was quite clear, from the news coming out of other countries, that mass gatherings were a risk to public health, this government allowed the Cheltenham Festival - with an attendance figure of around 250,000 - and the Liverpool/Madrid football match - with an attendance figure of around 54,000 - to go ahead, presumably in the name of profit.
