When 2 officers got involved, the average jumped to 4.98 rounds and with 3 officers or more to 6.48. The number of rounds fired per officer increases in multiple-officer shootings by as much as 45 percent over single-officer shootings, Aveni says. Again, he judges distance to be a likely factor. A higher volume of fire may be used to compensate for the lower hit ratio as distance increases, he speculates.
Subterranean rivers of London. The subterranean or underground rivers of London are the tributaries of the River Thames and River Lea that were built over during the growth of the metropolis of London. The rivers now flow through underground culverts.
The River Thames reaches a depth of about 37 feet at its deepest point. The Thames stretches some 215 miles from source to sea and is the longest river in England. The depth of the Thames varies considerably at different points along its course. The river has a depth of only about 5.9 feet at the London Bridge. According to Thames River Trust, the river features 190 small islands that are formed by dividing streams, silt and sedimentary deposits that occur in 18 catchments. The River Thames is fed by 38 main tributaries that include rivers, brooks and several underground streams.
