fingerprinting methods as part of a general inquiry into scientific evidence.
how can a fingerprint be transferred? a fingermark left on a greasy glass or some other smooth surface can be lifted with a strip of adhesive. it can then be deposited on another, perhaps incriminating, object. before 1973, fingerprints at the scene of a crime used to be photographed for identification purposes and the objects carrying the prints were shown in court as well. however, this is no longer necessary. since 1973, a new
method of taking prints has been used. police experts can now use a strip of adhesive tape to lift a print which is then produced in court as evidence. as a result, criminals are
accusing the police of lifting their prints and planting them at the scene of a crime. and lawyers are worried about this increasing number of claims.
according to the ex-chief of scotland yards fingerprint
department, mr. harold squires, more than 55% of the cases he now gets are making these claims. but so far he has not seen any fingerprint evidence that proves the allegations to be true. lifting a mark and putting it on another object requires great skill and trouble. its almost impossible but it can be done. it can usually be easily detected by experts, but there is a
chance that even experts may not be able to tell. so he would like the old method of photographing prints and producing them together with the objects to be generally used again.

i experienced a long roller-coaster ride in the stock market. so did a lot of my friends. in 1999, the bull dominated the stock markets in the states and stocks simply soared, dow and nasdaq reaching their historical heights respectively. in
particular, the technology sector grew like crazy. you did not have to be a technology guru to pick the right stock and get rich. you just picked any technology stock, at sheer blind
random, and you would gain after a short period of time. that was the time when most of us — i mean the circle of our friends — got into the stock market.
in connell, i had taken a couple of finance courses and learnt some basic concepts about stocks, such as buy low, sell high, diversify your portfolio and invest for the long term. however, being a green hand in this market, i found it terribly hard to apply what i learnt. first of all, it was difficult to make a due judgment on when the price hit the bottom and was about to turn upward. i had a watch list. some stocks just had the momentum from nowhere and kept on inching higher and higher; some just went headlong in the opposite direction. secondly, it was easy to say diversify your portfolio. but with my little savings that i invested in the market, it did not seem to make sense to divide a couple of thousand dollars among several stocks. when i tried to apply the evaluation theories to the stocks, they were outrageously expensive, especially those internet stocks. on the other hand, the stocks of traditional industries were punished really hard. they were cheap buys to me and fit the theory of buying low, but they seemed to always stay in the red, with no hope of turning green.
testing the water, i picked two stocks i believed had good fundamentals and were bargains. my husband, who
understood nothing about the market, decided to go in an opposite direction. he picked only one technology stock simply by watching the news and following the hot sector. i was really dubious of how well he would fare.
after the day we picked the stocks, we would keep our eyes on how the market did every
day. however, we had different reactions to the market. the market soared one day and tanked another day; and to its rhythm, my spirit rose to the sky and then fell into the hell. although i told myself i should not be so emotional since i invested for the long term, i could not help myself jumping at the small percentage of gain and stomping at the loss.
