How does the cell defend the body?
The cell defends the body by using 6 unique cells that work together to protect the body. One important detail about this process is that one cell called the monocyte hears chemical signals and transforms into macrophages or “big eaters” that eat the invaders and provoke fevers. Another cell is the neutrophil. These cells sacrifice themselves in order to swarm and slow down the invaders and slow the spread of infection. The cells work in a beneficial way; one example of this is the b cell that spies on the invader cells and makes antibodies which are like keys for the other cells in order to expose the invaders. The helper t cell sends signals to the b cells and tells them what antibodies are needed and keeps them working. Also, the t cell is the cell that uses the antibodies made by the b cells and destroys the invader cells. Finally, after all the invaders are gone, the natural killer cells dispose of the infected cells and the b cells store information about the invader so that they can get rid of it easier the next time.
How do police forces defend cities?
City police forces are not always good at defending the city. The first example of this is that they are not always well trained. This was shown by a recent study where detectives made many mistakes when investigating a crime. This means they were not trained well enough not to make mistakes, true, everybody makes mistakes, but more than a few mistakes on an investigation can lead to deadly results. Another interesting fact about police forces in cities is that they don’t avoid needless violence, they charge to it in some countries. One example of this is in the article “Armed police: Trigger happy”, it states “In 2012, according to data compiled by the FBI, 410 Americans were “justifiably” killed by police—409 with guns”. This means that lots of Americans were killed even though it could’ve been avoided as shown in another study where they found that in total, British police only fired their weapons 3 times in a year and no one was shot fatally. In addition, police can’t always be trusted as shown in a new strategy that requires police officers to wear cameras in some cities. Evidence from the article “Forcing America’s Weapons Police to Wear Cameras” where the author writes ““When researchers studied the effect of cameras on police behavior, the conclusions were striking. Within a year, the number of complaints filed against police officers in Rialto fell by 88 percent and "use of force" fell by 59 percent. “When you put a camera on a police officer, they tend to behave a little better, follow the rules a little better,” Chief William A. Farrar, the Rialto police chief told the New York Times.” This shows that the police are not very trustworthy because without the cameras, they used more force and there were more complaints filed against them. As it says in the article, “Something needs to police the police.” Finally, police forces are not always the right size, as a few cities just simply do not have enough money to have large police forces that can keep the bad guys in check. For example, in the article “Crime-Ridden Camden To Dump City Police Force”, it states “Last January, because of budget cuts, the city laid off almost half of his police force. Thomson says he lost his entire homicide unit and narcotics unit in one fell swoop… The only business that's lucrative in this 9-square-mile city is selling drugs, and the police say they can't keep up with the crime.” This means that without a bigger police force, more crimes are being committed and more people are being stolen from, or worse, killed.
Is the city or the cell better at defending itself?
It is clear that the cell is better at defending its body than the police is at defending the city. The city can learn to be more like the neutrophil in the area of slowing down crime but not making it fatal. To build on this idea, the city can learn to make sure that all the crime done by a certain group/person is gone before closing the case. Another lesson from the cell is to store information about criminals more effectively. Doing this would help because the next time the criminal pops up on the radar, they know their patterns and can get the criminal behind bars faster. In addition, the city can learn to work together better so that not a lot of police officers are needed as it is clear some cities cannot afford a lot of them. Just look at the cell, it only has 6 different types of cells yet it gets rid of invaders quickly and effectively.
