It depends; somewhat on the strategic situation, but also the public response. Few would consider a downed drone worth killing over (and those that would tend to be hair-on-fire types). But if something becomes a media circus, public opinion can shift rapidly. Consider for example the absurd freakout over Chinese spy balloons earlier this year - it was a convenient stick to beat the incumbent administration with during a slow news period, so it became The Most Important thing for a week.
