Just two weeks after the fatal shooting of US citizen Renée Good, federal immigration agents shot and killed 37-year-old ICU nurse Alex Pretti, also a US citizen, in the streets of Minneapolis last weekend.

But, if you are keen to show support and don't know where to start, here are some practical solutions – backed by key organisations.
