The news lately focuses on three topics that hold my interest:
--the murder trial of Dallas police officer Amber Guyger, who managed to go into an apartment other than her own, and shoot its unarmed resident, an African-American man;
--the newest scandal after the President of the United States asked a foreign leader to "do him a favor" and investigate a political rival while linking up with the President's personal attorney; and
--the work of activist Greta Thunberg, who took a cruise to the U.S. to speak to the United Nations and call for action about climate change.
