[GTA V] So what happened in the immediate aftermath of "Meltdown"?

Did Michael really just hastily bury all of the bodies of the Merryweather personnel and dispose of their weapons and vehicles before anyone especially the police showed up?

Based on a Bleeter post by Michael's neighbour, Hayden Dubose silencers were not being used and thus everyone heard this gun battle going on in a high-end neighbourhood.

Apparently yes.  

We know that the attack on Michael's house did not make the news.  The news reports after that night focused on the premiere of Meltdown, with no mention of a gunfight in Vinewood Hills, aside from the Bleeter post you mentioned.  So either the authorities did not know about this event, or it was covered up somehow.  

Now, granted, there might be some incentive for the government or for Merryweather to cover up this incident because it's not okay for Merryweather to be attacking a private citizen at his house, and it's also very embarrassing for Merryweather to have failed so spectacularly at their mission, which comes after quite a few setbacks for Merryweather. But ultimately a coverup is very unlikely because Michael is very wary of his true identity being discovered, so it's not plausible that he would cooperate with the authorities or with Merryweather to accomplish any coverup.  

So how did Michael hide the evidence of this attack?  Well, after he repelled the Merryweather mercs, he told his family that he's going to make a call.  The most likely recipient of this phone call would be Lester, who's got all kinds of connections with the underworld and thus would likely be able to mobilize the manpower needed to dispose of the bodies and clean up the crime scene.  Sure, it's a stretch that this could be accomplished before the police showed up, but then again Lester's pulled off other miracles before, such as being able to immediately locate people throughout San Andreas no matter where they are, and identifying Michael's payments to Dave Norton despite Michael now using a fake identity and transferring the money through multiple proxies.  So if anyone's going to help Michael pull off something like this, it'd probably be Lester.
