Good. I don't think one dramatic incident outweighs the importance of privacy for entire world.

I also am appalled the media continues to hype shootings and "terrorism" when they are insignificant and irrelevant to modern life (more people die slipping in the bathtub each year, yet the FBI isn't worried that the lack of bath-mats is a national threat).

Do the math - If the money spent on "terrorism" went to any other cause (e.g. healthcare) we'd save 10x the lives we already do.

Exactly, these cases are outliers. Yet so many people fail to realize that. Take for example kidnapping, which is the 1th worry for parents, yet in the real world it fall 5000th of the threats to children (by close relative), by stranger I don't think even makes it to the list. The real threat are car crashes, suicide, and drowning which are 1th, 2th and 3th I think. The same think applies to "terrorism", it would be much more efficient to apply the resources to other causes. I think this whole "war on terrorism" and "war on drugs" if just fear mongering that politicians use to try and get elected.

If it's an iPhone, law enforcement can basically throw the phone in the trash right now.

Not necessarily. iPhones that have iCloud backup Feds can get a court order to have Apple provide as the backups not encrypted with device keys.

If it's the device data they want and it's a 5s or later yeah that's likely to be difficult to get at without decapping the chip.

Will unlocking it actually benefit anyone or bring anyone back? No! Nor will it give any insight whatsoever into the next shooting..

What it will do is enable them to find someone or something else to blame (TV, Rock Music, Religion, Racial Hatred...) for a complete nut jobs actions and his access to automatic weapons and therefore exonerate the Gun lobby yet again..
