Input: Read this: The late nineteenth century also brought the systematic study of color theory, and particularly the study of how complementary colors such as red and green reinforced each other when they were placed next to each other. These studies were avidly followed by artists such as Vincent van Gogh. Describing his painting, The Night Cafe, to his brother Theo in 1888, Van Gogh wrote: "I sought to express with red and green the terrible human passions. The hall is blood red and pale yellow, with a green billiard table in the center, and four lamps of lemon yellow, with rays of orange and green. Everywhere it is a battle and antithesis of the most different reds and greens."

Input: Read this: According to Hampshire Constabulary figures, Southampton is currently safer than it has ever been before, with dramatic reductions in violent crime year on year for the last three years. Data from the Southampton Safer City Partnership shows there has been a reduction in all crimes in recent years and an increase in crime detection rates. According to government figures Southampton has a higher crime rate than the national average. There is some controversy regarding comparative crime statisitics due to inconsistencies between different police forces recording methodologies. For example, in Hampshire all reported incidents are recorded and all records then retained. However, in neighbouring Dorset crimes reports withdrawn or shown to be false are not recorded, reducing apparent crime figures. In the violence against the person category, the national average is 16.7 per 1000 population while Southampton is 42.4 per 1000 population. In the theft from a vehicle category, the national average is 7.6 per 1000 compared to Southampton's 28.4 per 1000. Overall, for every 1,000 people in the city, 202 crimes are recorded. Hampshire Constabulary's figures for 2009/10 show fewer incidents of recorded crime in Southampton than the previous year.
Question: Which statistics are debated because of the different ways various police forces record crime?

Output: comparative crime statisitics
