Obstruction of justice - Wikipedia, the free encyclopedia
Modern obstruction of justice, in United States jurisdictions, refers to the crime of offering interference of any sort to the work of police, investigators, regulatory agencies, prosecutors, or other (usually government) officials.
Another choice might be "perverting the course of justice", which is the equivalent in UK and Canada.
Interestingly, one of my bound reference works (Dietl/Lorenz) (which I hardly ever crack anymore what with all the stuff on them interwebs) offers a description instead of a 1:1 equivalent term, suggesting there is a world of nuance between obstruction, perverting and Strafvereitelung.
So any attempt at greater precision is likely attainable only at the expense of less clarity. The fact is that what we're experiencing right now is a top-down disaster. -Paul Krugman
