I'm sorry but I completely disagree.
For one, I would hope NOT to see on MSM when the police go door to door, as they have, to conduct interviews. I wouldn't want anything to compromise their investigation. IMO we should NOT be privy to which people are being questioned. They have already stated in their press reports that they have conducted X amount of personal interviews, and that's all we need to know.
For another, I think the inventions of the Internet and cell phones have vastly improved the ability of LE to investigate far and wide.
Before the Internet, this tragedy would be a one or perhaps two day story here in NYC. It's horrific, but would likely still be a local murder in a small town, and the news cycle here would be on to other things.
For LE, being able to check the victims' incoming and outgoing phone calls, ping their locations, read texts that the victims sent, put their LE website online, have online community discussion boards such as WS, be able to instantaneously mass distribute pictures of the car being sought, for the public to have multiple ways to contact LE rather than writing a letter or calling long-distance, plus a thousand other things, IMO gives an ineffable amount of information flow that didn't exist earlier.
The same way that the Internet creates problems, with instantaneous real life interactions, it conversely offers tools that are simply indispensable nowadays.
I knew two teenagers who went missing in July 1973 and have still not been found. If cell phones existed then, I believe the police would have found them right away, even if they were already deceased, just by following where the pings ended.
IMO
