This thread will stay polite. Period.
The first sign of macho chest-thumping, any variation on the words "Jack Booted Thug" or any discussion about specific tactics either to facilitate or ambush a dynamic entry, and this thread gets shut down.
Now.
One of the things that makes a discussion concerning dynamic entries difficult, is that many people (esp. the Media) apply the term 'no-knock' to any dynamic entry situation, when it doesn't technically apply.
For instance, if I knock on the door, announce, "Sheriff" and wait 30 seconds, one minute or two minutes before giving up and kicking in the door, this isn't a 'no-knock' situation. The majority of people and all of the Media will refer to it as a 'no-knock', though.
So. What is a 'no-knock' warrant? A 'no-knock' warrant is one where the presence of law enforcement is not announced prior to entry of a structure. It may, or may not, involve a dynamic entry. For instance, I have had information that a suspect is at a certain address, I have gone to that address at 4AM with a warrant, picked the lock on the back door, drifted through the house behind a set of NVG's until I located my suspect, flipped on the bedroom light, causing the suspect to wake up and find the barrel of an HK pointed between his eyes. At which time I announced, "Sheriff's Office. Warrant."
No-knock.
A 'dynamic entry', on the other paw, is the use of surprise, speed, sensory overload, and overwhelming presence to effect entry into a location and place any suspects inside in custody before they can mount an effective counter-response. Please note that any time the presence of law enforcement is announced prior to entry into the structure, the entry is not a 'no-knock', it is a 'knock-and-announce'.
Why do we use dynamic entry? Safety.
Inside of his house, a person is relaxed. Outside, the person is more alert, aware and mentally prepared.
Inside of a house, the walls and other structures obstruct lines-of-sight, allowing officers to get that much closer. Outside, the subject may have 360 line-of-sight, and can see officers well outside effective containment range.
Inside of a house, walls and other structures act to contain the subject and aid in preventing escape. Outside, the subject has much greater area available to utilize to elude and escape.
Should things go wrong, the walls floor and ceiling of a house act to limit the threat of weapons to uninvolved citizens, bulletstops, to be blunt. Outside, stray weapon fire can has uninterrupted access to innocent bystanders.
The inside of a house limits the potential for hostage-taking or uninvolved citizens from being put in danger. Outside, the potential for hostages increases greatly, and Condition White people will, I swear to God, wander between four officers with guns drawn facing down a critter who also has a gun drawn. Inside of a house reduces the chance that Grandma Frickert will blithely walk in front of your muzzle because you're blocking her way into the grocery store.
And then she'll file a complaint on you because you used profanity and a harsh tone of voice at her but that's a story for another day.
Inside of a house limits and controls the number of allies, witting or unwitting, available to the subject. Outside on the street, the number of allies and potential allies increases greatly.
Many violent subjects will be more apt to resort to violence when in the presence of an audience. In front of an audience, their reputation or 'face' may be at stake, and some critters will do stupidly violent things to avoid losing 'face' or having their reputation damaged. Also worth noting, some critters and/or situations can turn a potential audience into a mob, -- this is a Bad Thing.
Inside the house limits and controls the audience. Outside, on the street, not so much.
There are many other reasons, but that's a brief overview of why a dynamic entry may be chosen over another form of arrest or search.
